He received Ph.D. degree from the Department of Electrical and Computer Engineering at the University of Alberta in 2006. He then worked as a postdoctoral fellow in the iCORE Wireless Communications Laboratory at the same department. From 2007 to 2022, he worked as an Assistant Professor, an Associate Professor, and then a Reader in the School of Engineering at the University of Warwick. Currently, he is working as a Professor of Signal Processing and Communications in the Department of Engineering at the University of Durham. His research interests include wireless system design and analysis, integrated sensing and communications, UAV communications, backscattering, and statistical signal processing.
Talk Title: Integrated Sensing and Communications in Mixed Propagation Fields
Integrated sensing and communications (ISAC) is essential for the sixth-generation (6G) wireless systems. In contrast to most existing works that assume either the far field or near-field model for both communications users and sensing targets, this study addresses a new scenario where multiple targets and communication users exist in mixed near- and far-field regions. Both single-target bi-static case and multi-target mono-static case are investigated. Different optimization techniques are used to optimize the sensing-centric and communications-centric designs. Numerical results are given to highlight the trade off between mixed field communications and sensing, as well as the performance difference in different cases due to mixed field. They also examine how antenna size and transmit power affect sensing performance in mixed-field ISAC systems. In addition, our proposed design outperforms the benchmark in useful practical cases.
