Prof. Husheng Li of Purdue University

Joint communications and sensing (JCS), a.k.a. Integrated Sensing and Communications (ISAC), are expected to be a featuring technology in 6G wireless communication networks. It improves the efficiencies of spectrum and energy by sharing the same waveform for both tasks of communications and sensing. The waveform in JCS could be traditional communication waveforms (such as OFDM) or existing radar waveforms (such as FMCW). In this talk, we will discuss waveform design dedicated for JCS, which may go beyond existing waveform designs for individual systems. We focus on two questions, for the marriage of communications and sensing: (a) How to design a natural and enlightening framework for integrating both communications and sensing? To this end, we propose to consider JCS as a broadcast and thus unify several major designs within the same framework. (b) How to characterize the conflict and trade-off between communications and sensing when they are integrated within the same waveform? We will examine several types of conflict, such as randomness-determinism, environmental complexity, and coding-spreading trade-offs. Finally, I will provide an overview on my future research in the area of JCS.
