Summary: Direction finding has found use in many applications that include military or security, spectrum monitoring, geo-location and intelligent communications like SDMA. It is an indispensable first step in most radio-detection systems. Multi-antenna systems make direction finding easier and reliable. As the source signal reaches an antenna array, one can take advantage of the variations in the received signal at each antenna, together with the knowledge of the array characteristics, to determine the direction of arrival of the signal. This approach requires the antennas to be calibrated and synchronized, and achieving this, is a challenge. This Webinar provides an overview of the practices and methodologies employed in direction finding particularly for communication systems, highlighting their advantages and drawbacks. An overview of a 128-antenna massive MIMO testbed will also be given to provide an example of how practical direction-finding research could be conducted.

Paul Harris, University of Bristol. The focus of Paul’s PhD has been to evaluate the real-world performance of massive MIMO. Within the Communication Systems & Networks (CSN) Group at the University of Bristol, he is the lead researcher and systems engineer for a 128-antenna massive MIMO testbed. Working in collaboration with Lund University and National Instruments, Paul led two research teams to set spectral efficiency world records in 2016. For this achievement he received 7 international awards from National Instruments, Xilinx and Hewlett Packard Enterprise, and an honorary certificate of appreciation from the IEEE Communications Society Student Competition for “Communications Technology Changing the World”. He was also recently consulted for technical input on a video produced by the IEEE Spectrum titled “Everything you need to know about 5G”.
Benny Chitambira, University of Bristol. Benny graduated with a BSc Honors in Electrical Engineering from The University of Zimbabwe in 2003. He worked for 3 years in IT with senior roles in projects & operations management; broadband communications; and ISP engineering, before undertaking postgraduate studies at The University Nottingham where he graduated with an MSc Electronic Communications and Computer Engineering in 2008. After that, he spent some time in IT as a Systems Engineer with primary responsibilities in network and storage engineering.
