Spectrum Monitoring Receiver from Digilogic Systems

Introduction:

In today’s increasingly complex RF environments, efficient and precise spectrum monitoring is essential. Spectrum monitoring is a critical process in managing and optimizing the use of radio frequencies across various applications, including telecommunications, aerospace, and defence. By continuously observing the radio frequency spectrum, spectrum monitoring ensures compliance with regulatory standards, identifies unauthorized transmissions, and detects potential interference sources. 

Advanced Spectrum Monitoring Receiver systems utilize advanced technologies to analyze real-time frequency data, ensuring reliable performance and preventing service disruptions, safeguarding the spectrum, and enhancing communication infrastructure.

What is spectrum monitoring?

Spectrum monitoring is performed by utilizing up-to-date highly integrated PXIe-based systems to demodulate and analyse digital and analog RF/IF signals. These systems which have been created in LabVIEW and utilizing Virtex- 5 FPGA technology, can acquire up to six signals from NI PXIe monitoring receivers. 

Some of these figures include the spectrum and small satellite mapping, the use of Waterfall/Spectrogram real-time probe, and RAID for post-analysis. Operations like ‘channelizing’ and ‘demodulation’ facilitate fine-tuning and selective filtering and decoding of the signals according to the characteristics set by the user.

Why is spectrum monitoring important?

Spectrum Monitoring Importance

 Detects interprets, and successfully controls radio communication frequency signals.

Promotes proper use of the available spectrum and identifies those who are using the frequency without authority.

Reduced interference of the communications that are central to the functioning of the system.

Channelization: The signals that are down converted are further partitioned into six independent paths for parallel processing.

Signal Analysis: Regarding the signal acquired in each channel, signal processing is applied by utilizing numerous methods on LabVIEW.

Visualization: Spectrum and waterfall are typical types of displays that give immediate information regarding signals.

What technologies are used in Digilogic Systems spectrum monitoring systems?

Spectrum monitoring systems of Digilogic Systems are designed using PXIe architecture, LabVIEW software, and Virtex-5 FPGA for effective signal analysis. These include live images of the panoramic spectrum, spectrogram displays, and recording/playback functionalities. Sophisticated channelizing and demodulation allow for processing up to six signals at a time with separate bandwidth settings.

What are the key applications of Digilogic Systems spectrum monitoring?

The main use is found in the areas of communications such as telecommunication, aerospace, and defence to the set legal requirements. Frequency supervision aids in

The administration and identification of unauthorized uses as well as signal jamming in those sectors of operation.

Conclusion:

The Spectrum Monitoring Analyser of the Digilogic System is an efficient and multifunctional device for performing various types of RF/IF signal analysis. The use of PXIe as the basis for the system together with being integrated with LabVIEW software and Virtex-5 FPGA provides signals’ high-quality processing. As the system can handle up to six signals at a time, this means that the variety of waveforms is encompassed by the system.

The ability to analyze signal characteristics in a real-time waterfall and panoramic spectrum display is also very useful. In addition, the recording and replay function prepared for offline examination is particularly useful in this regard. Because users can alter the parameters of channelization and demodulation, it becomes possible to derive usable information from the received signal. In summary, Digilogic’s analyzer is a valuable tool for researchers and engineers who are solving problems in the RF and communications fields.

He is a member of the board of directors for the Dynamic Spectrum, Wi-SUN, and WhiteSpace alliances and the author of Simulation and Software Radio for Mobile Communications.

THE CHALLENGE

We needed to develop a comprehensive evaluation system that implements our proposed universal time-domain windowed OFDM (UTW-OFDM) in an actual LTE system to demonstrate feasibility and practicality. Implementing the UTW-OFDM requires modification and/or customization of the modem IC, which is costly and time- consuming. In addition, IC-based implementation constrains the flexibility of the experimental evaluation during which we need to optimize parameters for various conditions.

THE SOLUTION

We developed the Real-time Wave-shaping System shown in Figure 2 with off-the-shelf LTE components. Using this system, we successfully conducted the world’s first demonstration of a UTW-OFDM-based LTE system. Our proposed UTW-OFDM can reduce the OOBE by about 20 dB at channel edges without any throughput deterioration. Our results also showed that the UTW-OFDM is highly compatible with the conventional CP-OFDM since we established the communication link without modifying the receiver. All in all, the proposed UTW-OFDM can help smooth the transition from 4G systems to 5G and beyond systems.

The Real-time Wave-shaping System, which includes the RF transceiver unit, the baseband signal processing unit, and the control unit, can be easily designed and implemented using the NI platform and solutions. We incorporated LabVIEW software as a graphical system design tool and FlexRIO hardware to create a systematic software defined radio development platform. We reduced the development cost by more than 90 percent, and the development period was only three months.

WHAT’S NEXT

We are evaluating system performance using a fading emulator, assuming a real communication environment. In parallel, we will soon perform field experiments to emit radio waves by attaching antennas to the UTW-OFDM- based LTE system.

Flexible Real-Time Waveform Generator for Mixed-Service Scenarios

Providing a Unified FPGA Implementation for On-the-Fly Reconfigurable Waveform Generation

Martin Danneberg; Ahmad Nimr; Maximilian Matthe; Shahab Ehsan Far; Ana-Belen Martinez; Zhitao Lin; and Prof. Dr. Gerhard Fettweis, Vodafone Chair for Mobile Communications Systems, Department of Electrical Engineering and Information Technology, TU Dresden

USER PROFILE

Martin Danneberg received his master’s degree in electrical engineering from TU Dresden in 2013. Since September 2013, he has led the research activities for the EU projects CREW, eWINE, and ORCA as a member of the Vodafone Chair. His professional interests include nonorthogonal waveforms for future communication systems, especially FPGA-based prototype implementations of flexible multicarrier modulation schemes.

Prof. Dr. Gerhard P. Fettweis earned his doctorate from RWTH Aachen in 1990. Since 1994, he has served as the Vodafone Chair Professor at TU Dresden, with 20 companies from Asia, Europe, and the United States sponsoring his research on wireless transmission and chip design. In Dresden, he has spun out 11 start-ups and set up funded projects generating close to a half billion euros.

THE CHALLENGE

Wireless networks operating in unlicensed bands suffer because multiple radio technologies share one frequency resource, which causes cross-technology interference. However, to connect all applications, various technologies must be supported in industrial scenarios. One step toward solving those challenges is to use a unified flexible physical layer (PHY) chipset and connect it with multiple chipsets to interlink the different wireless nodes. Since a single flexible chipset is used, its signal processing parameters must be reconfigured quickly to emulate the different radio access technologies.

THE SOLUTION

The Vodafone Chair for Mobile Communications Systems at Technical University Dresden used NI rapid prototyping SDR tools and the LabVIEW Communications System Design Suite to develop a flexible PHY transmitter based on real-time FPGA processing. The prototype supports waveform generation for diverse systems such as WiFi, Bluetooth and ZigBee, LTE, and 5G. Moreover, the implementation is runtime-configurable, meaning that the frame structure can be changed arbitrarily between frames without delaying the ongoing transmission. Such flexibility is mandatory for optimally using available time-frequency resources by aligning different services in time and frequency without delay when switching between different waveforms.

WHAT’S NEXT

We will verify the implementation in real applications such as seamlessly switching between streaming and low- latency services. Moreover, we will unify the FPGA interface implementation to ease the host-side configuration.

In-Band Full-Duplex SDR for MAC Protocol With Collision Detection

Dr. Sofie Pollin, Professor; Dr. Tom Vermeulen, Solution Engineer; and Seyed Ali Hassani, PhD Researcher, Networked Systems Group, KU Leuven

USER PROFILE

Dr. Tom Vermeulen obtained his bachelor’s and master’s degrees in electrical engineering from KU Leuven in Belgium. He researched in-band full-duplex SDR under the supervision of Dr. Sofie Pollin in the Networked Systems Group. In 2016, as a visiting scholar at UCLA, he worked on simultaneous transmissions and collision detection. He obtained his doctoral degree and joined Proximus in 2017.

Seyed Ali Hassani obtained his bachelor’s degree in electrical engineering from Arak Azad University in Arak, Iran, in 2008. He then worked as an R&D engineer in industry to gain his professional experience. Hassani earned his master’s in information technology/signal processing from Tampere University of Technology in Finland in 2016. He is a doctoral candidate at KU Leuven focusing on vehicular networking.

Dr. Sofie Pollin obtained her doctorate at KU Leuven in 2006. She returned to imec to become a principal scientist in the green radio team in 2008. In, 2012, she became an assistant professor in the electrical engineering department at KU Leuven. Pollin researches networked systems that require networks that are more dense, heterogeneous, battery powered, and spectrum constrained.

THE CHALLENGE

Because the number of wireless devices has been increasing rapidly over the last year, ultra-efficient protocols are needed to share the spectrum fairly and efficiently. Wireless networks also must satisfy latency constraints and minimize energy consumption.

THE SOLUTION

We exploited the bidirectional capability of in-band full-duplex radio to detect signal collisions and interference. As soon we determined a MAC frame was erroneous, we aborted the frame transmission to save spectrum and energy resources. Basically, full-duplex technology enables a radio to transmit and receive simultaneously and in the same channel. We can use this listen-while-transmit capability to assess the channel in transmission time. In this case study, we implemented a real-time collision detector based on the statistical evaluation of the received signal. Our novel Full-Duplex Carrier Sense Multiple Access with Collision Detection (FD CSMA/ CD) MAC can improve the network throughput fivefold and reduce the energy consumption by 50 percent, as noted in our presentation “Performance Analysis of In-Band Full-Duplex Collision and Interference Detection in Dense Networks,” at 2016 IEEE Annual Consumer Communications Networking Conference. For prototyping, we accelerated our implementation using NI USRP devices and the LabVIEW Communications System Design Suite.

WHAT’S NEXT

We are working on improving the sensitivity of the collision detector using deep learning. We hope to provide experimental results for a network of five full-duplex-capable nodes to support outdoor scenarios.

He has been teaching and researching communications circuits and systems for over three decades and has published widely in these areas. He works as a consultant to various industries and governmental and legal organisations worldwide.

THE CHALLENGE

Billions of devices will soon be connected to the Internet in line with the vision of the Internet of Things (IoT). This means 5G must make highly efficient use of the wireless spectrum. Spectrally efficient frequency division multiplexing (SEFDM) has the potential to make better use of the spectrum through bandwidth compression but at the cost of higher levels of interference. Our challenge was to create a real-time testbed, on a popular platform, for SEFDM to be investigated widely.

THE SOLUTION

We demonstrated the world’s first real-time SEFDM system using USRP RIO and the LabVIEW Communications System Design Suite. The key innovation was in the deployment of a novel real-time channel estimation and equalisation algorithm, combined with a real-time iterative detector. Our system compressed transmitted signal bandwidths by up to 60 percent to offer significant bandwidth savings relative to the multicarrier signals used in current communication systems. By working with various modulation formats, the system allowed for testing in 5G scenarios. We used two USRP devices, one for the transmitter and the other for the receiver. We programmed the transmitter and receiver using LabVIEW and then directly programmed the FPGAs to facilitate speed and flexibility. We implemented over-the-air testing using antennas and completed more demanding tests using a channel emulator.

WHAT’S NEXT

Multiantenna systems will be constructed and bandwidth will be extended to transmit at much higher frequencies (mmWave) and deploy in real-life scenarios with multimedia signals. We will be able to compare these systems with existing wireless standard systems and show their advantages.

Building 64×64 MIMO Parallel Channel Sounder Hardware Based on the CDMA Method Using NI PXI Modular Instruments and Post-Processing Software

Haowen Wang and Dr. Yang Yang, Shanghai Research Center for Wireless Communications

USER PROFILE

Haowen Wang is a senior engineer at the Shanghai Research Center for Wireless Communications (WiCO). He received bachelor’s and master’s degrees in computing and software from Fudan University in Shanghai in the People’s Republic of China. As a LabVIEW champion, he has more than 13 years of LabVIEW development experience. His interests include RF data acquisition, channel measurement, and verification and test solutions.

Gui Yunsong is a senior system engineer at the Shanghai Institute of Microsystem and Information Technology (Chinese Academy of Sciences). He has worked as a senior baseband algorithm engineer in Huawei for many years. He has 15 years of experience in wireless communication system design. In recent years, his research has focused on 5G communication demo system design using the SDR platform.

THE CHALLENGE

As the number of transmitting and receiving antennas increases, it is crucial that we capture dynamic channel characteristics and develop realistic channel models to achieve spectrum and energy efficient design (SEED) objectives in future wireless networks. This difficult task includes:

■ Picosecond-level synchronization across multiple channels

■ Real-time storage of multiple raw channels of measurement data

■ High-speed parallel calibration methods to compensate for nonideal channel responses

■ High-accuracy channel parameter estimations based on aliasing MIMO channel signals

THE SOLUTION

We developed our parallel channel sounder platform using NI products for sub-6 GHz spectrum and millimeter wave. It supports 8×8 paths (can be extended to 64×64) and 200 MHz/ch bandwidth under sub-6 GHz and supports 2×2 and 2 GHz/ch bandwidth at the millimeter-wave band. Our platform addresses the above challenges with the following features:

■   Picosecond-level synchronization—To achieve  accurate AoA/DoA estimation, we  designed  a synchronization method to limit misalignment across all TX/RX channels to around a 30 ps reference like NI-TClk technology.

■ 51.2 Gbps parallel data streaming—Our DMA-FIFO-based data-streaming method can take advantage of the huge bandwidth of the backplane bus and use zero-copy technology to effectively reduce delay by avoiding extra copies and state transitions.

■ High-speed calibration method—Different from traditional methods, our MIMO calibration can quickly achieve a MIMO RF channel’s response by transmitting a PN sequence through a MIMO coupler, whose frequency response is measured before, separating at the receiver side only once.

■ www.wise.sh—We set up an online shared open channel measurement database for research. It features all the data measured by the parallel channel sounder platform.

WHAT’S NEXT

In terms of software, we will finish verifying estimation results by comparing the results from measurement with ray-tracing software. In terms of the sounder platform, we will extend the system to 64×64 channels under sub-6 GHz and extend to a 110 GHz channel sounder at the millimeter-wave band.

Distributed Massive MIMO: Algorithm for TDD Reciprocity Calibration

Liesbet Van der Perre, Guy A. E. Vandenbosch, and Sofie Pollin, Professors; Cheng-Ming Chen and Andrea P. Guevara, PhD Researchers; and Vladimir Volskiy, Postdoctoral Researcher, Networked Systems Group, KU Leuven

USER PROFILE

Cheng-Ming Chen received his master’s degree from GICE in NTU, Taiwan, in 2006. He has worked as a baseband design engineer for WiMAX and LTE in ITRI and a senior system design engineer at BRCM, where he mainly focused on Wi-Fi receiver performance verification. He is a doctoral candidate at KU Leuven investigating real-world propagation characteristics of distributed Massive MIMO with an NI testbed.

Dr. Sofie Pollin obtained her doctorate at KU Leuven in 2006. She returned to imec to become a principal scientist   in the green radio team in 2008. In, 2012, she became an assistant professor in the electrical engineering department at KU Leuven. Pollin researches networked systems that require networks that are more dense, heterogeneous, battery powered, and spectrum constrained.

THE CHALLENGE

We need a large-scale Massive MIMO channel model. We know that distributed Massive MIMO exploits diversity more efficiently and can potentially offer much higher probability of coverage, but we still face the challenges of backhaul, synchronization, and time division duplex (TDD) reciprocity calibration. Our work focuses on an algorithm to improve TDD reciprocity calibration for equally distributed collocated arrays.

THE SOLUTION

We created the distributed systems by connecting our two 32-antenna testbeds to the main chassis with a 10 m optical fiber cable using NI USRP RIO, LabVIEW Communications Systems Design Suite, and MIMO Application Framework. We can use the hierarchical-based calibration method to address the huge dynamic range between the channel gain of intra subarrays and inter subarrays. To increase diversity and array gain during intercluster calibration, we can apply maximum ratio combining and maximum ratio transmission. Therefore, unlike when using the conventional method, we can collect all multiple input single output (MISO) gain in one shot during intercluster calibration. We can use distributed antenna arrays to help decorrelate closely collocated users in both LoS and NLoS scenarios.

WHAT’S NEXT

We want to emulate the pilot contamination effect using two cells that share the spectrum. Based on the channel characteristics, we can efficiently assign pilots in two virtual cells and reduce pilot contamination. We can also use frame structure modification to reduce pilot contamination. With the virtual two-cell testbed, we can evaluate the performance in the real world.

*This case study features joint work with Dr. Seong-Lyun Kim at Yonsei University.

THE CHALLENGE

We tried to alleviate the spectrum crunch by canceling out self-interference, optimizing pilot patterns and synchronization, and defining proper decisions based on an opportunistic map (OP MAP).

THE SOLUTION

We created the first implementation of OP MAP-based flexible hybrid-duplex systems in sensor-aided cognitive radio networks to maximize system throughput and spectral efficiency. It offers stochastic geometry-based OP MAP calculation with LTE-based full- and half-duplex radios based on the LabVIEW Communications LTE Application Framework.

SYSTEM SCENARIO

The system features a sensor-aided mode, specifically for Internet of Things (IoT) applications, based on device-to- device (D2D) communications. We can use a full-duplex technique to enable more efficient network sharing. We also can conduct testbed experiments indoors and network simulations for outdoor scenarios. The system uses one sensor-based opportunistic algorithm with random MAC decision making.

SYSTEM ARCHITECTURE

The system architecture is designed to sense the interference level at a sensor’s location. It converts the sensing database to an OP MAP to determine whether to transmit the signal. It distributes the OP MAP from the server to secondary nodes to allow the operation of hybrid-duplex radios (full-duplex, half-duplex, and silence modes).

WHAT’S NEXT

Now we are enlarging our algorithm to make a more practical implementation that can manage multiple users with full-duplex radios. Also, we are applying it to wideband matters to achieve high system throughput and verifying results by comparing it with 3D ray-tracing software.

An Experimental SDR Platform for In-Band D2D Communications in 5G

Max Engelhardt and Dr. Arash Asadi, Technische Universität Darmstadt

USER PROFILE

Max Engelhardt holds a master’s degree in IT security from Technische Universität Darmstadt in Germany. He works as a student assistant at the Secure Mobile Networking Lab (SEEMOO). His research interests include security in wireless networks, 5G cellular networking, device-to-device (D2D) communication techniques, and software defined radio (SDR) prototyping.

Dr. Arash Asadi received his doctorate in telematics engineering from Carlos III University of Madrid (UC3M) in 2016. He joined SEEMOO at Technische Universität Darmstadt in March 2016 as a postdoctoral researcher. His research interests include 5G cellular networking, millimeter-wave communication, D2D communication techniques, and SDR prototyping.

THE CHALLENGE

D2D communications has been shown to significantly improve spectral and energy efficiency in cellular networks; thus, it is considered a key feature in forthcoming 5G networks. Despite growing research interest on this topic, academia is still lacking important tools to evaluate and further explore the potential of D2D communications under realistic conditions. This is especially true for in-band D2D communications, for which the D2D link must use licensed cellular frequencies.

THE SOLUTION

We based our experimental SDR platform on the NI USRP RIOs and LabVIEW Communications LTE Application Framework, which we extended to allow one eNodeB to serve multiple user equipment (UE) devices simultaneously using orthogonal frequency division multiplexing access (OFDMA). We further extended the framework’s UE design to feature multiple OFDMA-multiplexed uplink transmissions and an uplink receiver. These extensions enabled us to use part of the uplink spectrum for a D2D channel between UE devices. Our system can operate in one of two modes. In Legacy Downlink Mode, the eNodeB transmits each UE device’s payload data directly to the respective UE. In D2D Relay Mode, it sends both UE devices’ payload data to the UE device with the better downlink channel, which then relays the other UE device’s payload via the D2D channel. Our eNodeB features a lightweight, quality- aware scheduler that allows dynamic switching between the two modes based on reported channel qualities.

WHAT’S NEXT

To further improve our platform, we are exploring the integration of outband frequency bands into our system and decentralized scheduling approaches, during which UE devices can organize D2D transmission in the absence of cellular infrastructure.

Wideband Multi-channel Signal Recorder for Radar Applications

Achieving Multisite Synchronous and Coherent RF Signal Acquisition and Recording With a LabVIEW Application When Synchronized to a GPS Time Reference

Bartosz Dzikowski, Marcin Baczyk, Łukasz Mas´ likowski, and Jedrzej Drozdowicz, Institute of Electronic Systems, Warsaw University of Technology

USER PROFILE

Bartosz Dzikowski received his Dipl. Ing. degree in technical physics from Nicolaus Copernicus University in Torun´ , Poland, in 2013, and his master’s degree from the Warsaw University of Technology in 2016. He is a LabVIEW developer and a doctoral student at the Warsaw University of Technology.

Marcin Kamil Baczyk obtained his master’s degree in 2011 from the Faculty of Electronics and Information Technology at the Warsaw University of Technology. His research interests include digital signal processing for radar and radar experiments carried out both in the laboratory and outdoors, including ground-scattering measurements. He works on inverse synthetic aperture radars, passive radar, and radar tomography.

THE CHALLENGE

To conduct radar research, we needed to acquire RF signals coherently from multiple channels. We also had to know how to stream that acquired data to disk for offline analysis or implement online live processing, which involves handling gigabytes of data per second. In applications like multistatic radars, we needed a multisite and coherent RF recording not only to synchronize channels at one site but also to synchronize channels and provide high-phase stability across different sites that can spread over many kilometers.

THE SOLUTION

We developed the wideband multichannel signal recorder, which is a LabVIEW application that coherently acquires RF signals from NI devices. The recorder provides waveform streaming to a RAID disk and enables us to preview signals and their spectra before and during the acquisition. It supports up to 10 measurement channels of NI-RFSA or NI-USRP devices. When we use NI PXIe-6674T (timing) and PXIe-6683H (GPS) modules, we can synchronize the measurement system to the GPS time reference and trigger it precisely at a given time. This allows multisite synchronous and coherent RF recording, which is particularly important in multistatic radar research. Moreover, the application works with the NI-PXImc driver software interface, which allows online data streaming to a processing unit and implementing a real-time radar. NI hardware and our LabVIEW recorder make building a radar faster, cheaper, and easier.

WHAT’S NEXT

Users can create their own measurement scenarios, implement a processing procedure to create an online radar, or stream recorded waveform to a RAID disk and analyze it offline. In the future, more acquisition devices will be supported to increase bandwidth and offer a range of possibilities.

Passive and Active Radar Imaging

Designing and Testing Passive and Active Synthetic Aperture Radar (SAR) Demonstrators With NI Software Defined Radio (SDR) Hardware

Damian Gromek, Dr. Piotr Samczynski, Piotr Krysik, and Krzysztof Kulpa, Research Lab on Radar Techniques, Institute of Electronic Systems, Warsaw University of Technology

USER PROFILE

Damian Gromek received his master’s degree in electronics from the Warsaw University of Technology in Poland in 2011 and has been a doctoral candidate there ever since. He is working as a research assistant, and his research interests are radar signal processing, active and passive SAR, and passive radar.

Dr. Piotr Samczynski received his bachelor’s and master’s degrees in electronics and doctorate degrees in telecommunications all from the Warsaw University of Technology. Dr. Samczynski’s research interests are in the areas of radar signal processing, passive radar, synthetic aperture radar and digital signal processing.

THE CHALLENGE

We needed to design and test innovative active and passive SAR demonstrators in a short amount of time. SAR allows us to obtain a 2D image of the ground landscape. The classical SARs are active radars, which illuminate the targets using their own transmitters. The new trend in radiolocation is passive radar technology, which uses an existing net of transmitters of opportunity to illuminate the target for imaging purposes.

THE SOLUTION

By combining NI SDR hardware with commercial off-the-shelf (COTS), we could quickly design and test active and passive radars. During our research, we tested both passive and active SAR imaging technologies. In both solutions, we built the demonstrators using NI USRP hardware. We built an active radar as a frequency modulated continuous wave (FMCW) radar. In this solution, one Tx channel emits signals and the second Rx channel receives radar echoes. This results in a 2D image of the ground landscape. In the second, passive radar solution, the USRP uses only the Rx channels of USRP devices to collect reference signals from DVB-T transmitters of opportunity, and we used surveillance signals reflected from targets. We’ve validated both demonstrators in real conditions using an airborne platform as a radar carrier.

WHAT’S NEXT

The higher bandwidth of the generated signal gives the higher range resolution; therefore, the solutions with 1 GHz and higher bandwidths are most interesting. In addition, we’re interested in the higher bands for active radars (for example, X and K bands).

Multiantenna Technology for Reliable Wireless Communication

Comparing Multiantenna Techniques for V2X and UAV Communications Using Live LTE Network Signals Recorded by a USRP-Based Channel Sounding Measurement Setup

Madalina C. Bucur, Tomasz Izydorczyk, Dr. Fernando M.L. Tavares, Carles Navarro-Manchon, Gilberto Berardinelli, and Preben Mogensen, Wireless Communication Networks Section (WCN), Department of Electronic Systems, Aalborg University

USER PROFILE

Dr. Fernando M.L. Tavares received his master’s degree from the University of Brasilia in Brazil and his doctorate degree from Aalborg University in Denmark. Both degrees focused on wireless communications. He is an assistant professor at the WCN at Aalborg University and visiting researcher at Nokia Bell Labs Denmark. His research interests include MIMO, interference management, and advanced transceiver design.

Tomasz Izydorczyk received his master’s degree in mobile communications from Telecom-ParisTech/Eurecom. His thesis focused on unlicensed spectrum extensions for NB-IoT. In 2016, he was a research intern with Intel Mobile Communications. He is pursuing a doctorate degree supervised by Preben Mogensen at Aalborg University. His research interests include the potential use of MIMO techniques for URLLC and UAV communications.

THE CHALLENGE

Multiantenna signal combining techniques like minimum mean square error (MMSE) improve signal reception performance, but they don’t work well in highly interfered scenarios. Alternatively, multiantenna receivers estimating the direction of arrival (DOA) of incoming signals can tell the difference between desired and interfering contributions, which enables efficient beam steering toward the intended direction(s). The emergence of new use cases for vehicular communication presents new opportunities to exploit advanced multiantenna techniques on the user equipment (UE) side. We aimed to experimentally validate the potential of such techniques for vehicle and drone use cases.

THE SOLUTION

We designed a USRP-based channel sounding measurement setup (Figure 1) with a 16-antenna circular array to estimate the spatial characteristics of the radio channel. We used it for measurements in a variety of vehicular scenarios (for V2X, the equipment was installed on a van; for UAV, it was lifted up 40 m high by a crane). The setup was designed to estimate the DOA of live LTE signals so we could derive the spatial distribution of intercell interference in a real LTE network. The measurement methodology consisted of recording I/Q samples and post- processing them to extract the cell-specific reference symbols (CRS) from the LTE time-frequency grid. Then we used the channel estimates to approximate multipath components (direction, power, and delay) from desired and interfering signals using algorithms such as MUSIC and SAGE.

WHAT’S NEXT

We will compare beamforming techniques (digital/analog) with multiantenna signal combining solutions. Then we will use that set of measurements to derive the statistical information for the spatial interference distribution. The goal is assessing the effective benefits of large antenna arrays on the UE side in real scenarios.

Radio Propagation Analysis for the Factories of the Future

Analyzing the Lower Percentiles of Radio Channel Statistics (Ultra-Reliable Regime) With Limited Effort Using Multinode Multiantenna Channel Sounding

Dereje A. Wassie, Emil J. Khatib, Dr. Ignacio Rodriguez-Larrad, Gilberto Berardinelli, Troels B. Sørensen, and Preben Mogensen, Wireless Communication Networks Section (WCN), Department of Electronic Systems, Aalborg University

USER PROFILE

Dereje Assefa Wassie received his bachelor’s degree in electrical engineering from Jimma University in Ethiopia and his master’s degree in telecommunication engineering from Aalborg University in Denmark. He is pursuing a doctorate degree in wireless communication from the Department of Electronic Systems at Aalborg University. His research interests include measurement system design and the experimental analysis of 5G communication concepts.

Dr. Ignacio Rodriguez-Larrad received his doctorate degree in wireless communications from Aalborg University. He is a postdoctoral researcher at the same institution, working in close collaboration with Nokia Bell Labs. His main research interests are radio propagation, channel modeling, ultra- reliable and low-latency communications, and industrial IoT. He is a corecipient of the 2017 IEEE VTS Neal Shepherd Memorial Award.

THE CHALLENGE

The Fourth Industrial Revolution aims to make factories smart by coordinating disparate cyber-physical systems. Wireless technologies (key enablers for flexibility, cost reduction, and mobility in the factories of the future) must therefore provide reliable communication among the different agents. Because industrial environments are complex radio propagation scenarios, predicting the performance of wireless systems requires measurement campaigns that are extensive enough to capture rare events in the tails of the channel statistics (ultra-reliable regime).

THE SOLUTION

We developed a channel sounding testbed using NI hardware (USRP-2953) and LabVIEW software. The testbed was composed of 12 transceiver nodes with 4×4 MIMO capabilities. With a TDMA transmission scheme, we measured the channel responses between all the testbed nodes at 2.3 GHz and 5.7 GHz carrier frequencies using 24 MHz wideband sounding signals. By performing only a few redeployments, we acquired many spatially relevant samples with limited effort. For example, covering all possible combinations over 24 spatial positions, which takes six redeployments and approximately three hours, we obtained a total of 24 x 23 x 16 = 8832 independent radio link samples. With this number of samples, we obtained insights on the channel statistics close to the 10-4 percentile, which is representative of the 99.99 percent of spatial availability.

WHAT’S NEXT

We will perform more measurements in industrial scenarios. Because we designed the testbed to be flexible, these new measurements can encompass different frequencies, different antenna configurations, and different frame structures for the TDMA transmission. Furthermore, we are developing additional features for experimental verification of envisioned 5G technology components within the H2020 ONE5G project.
