ECE Graduate Bo Li (2017 PhD) has been selected to receive the 2020 IEEE Signal Processing Society Young Author Best Paper Award for the paper "Optimum Co-Design for Spectrum Sharing between Matrix Completion Based MIMO Radars and a MIMO Communication System", IEEE Transactions on Signal Processing, September 2016 that he co-authored with ECE Professors Athina Petropulu and Wade Trappe.
The paper addresses the ever-growing need for bandwidth that wireless devices face by allowing sharing of spectrum with radars. The authors show that spectrum that was previously reserved for radar can be used to share spectrum between radar and communication systems. To reap the advantages of the available spectrum, the interference between the two systems must be managed. While managing interference is a classic problem in the radar and communication community, prior to this paper there had been very little work that jointly examined interference between these two different types of technologies. This paper (along with some earlier conference versions of it by the authors) introduces a new line of research for cooperative design of the two systems that aims to control interference between radar and communication systems. Compared to non-cooperative approaches in the literature, the proposed approach can improve spectrum utilization because it introduces more degrees of freedom. In particular, the paper jointly optimizes the signaling schemes of a MIMO radar based on sparse sensing and matrix completion (MIMO-MC radar) and a communication system. The result is that interference is minimized while both systems meet their operational objectives.
This work was part of Bo Li’s PhD thesis, for which he also received the 2017 Robert T. Hill Memorial Best Dissertation Award, given by the Institute of Electrical and Electronics Engineers (IEEE) Aerospace and Electronics Systems Society (AESS). Bo is currently working on radar based perception for autonomous vehicles at Aurora. He and co his ca-authors will be recognized at the Awards Ceremony at the IEEE International Conference on Acoustics Speech and Signal Processing (ICASSP) 2021 in Toronto, Canada.
Congratulations to Bo, Athina and Wade!
