Signal Processing for Joint Radar-Communications

January 19 @ 3:00 pm - 4:00 pm

: In this talk, we focus on the recent developments toward integrated sensing and
communications (ISAC). We consider a broad definition of coexistence, which covers ISAC,
collaborative communications, and sensing with interference. Toward fully realizing the
coexistence of the two systems, optimization of resources for both new/futuristic sensing and
wireless communications modalities is crucial. These synergistic approaches that exploit the
interplay between state sensing and communications are both driving factors and opportunities
for many current signal processing and information-theoretic techniques. In addition, a large
body of prior works considers colocated ISAC systems while distributed systems remain relatively
unexamined. Building on the existing approaches, the tutorial focuses on highlighting emerging
scenarios in collaborative and distributed ISAC, particularly at mm-Wave and THz frequencies,
highly dynamic vehicular/automotive environments that would benefit from information
exchange between the two systems. It presents the architectures and possible methodologies
for mutually beneficial distributed co-existence and co-design, including sensor fusion and
heterogeneously distributed radar and communications. The tutorial also considers recent
developments such as the deployment of intelligent reflecting surfaces (IRS) in ISAC, 5G systems,
passive internet-of-things, and ISAC secrecy rate optimization. This tutorial aims to draw the
attention of the radar, communications, and signal processing communities toward an emerging
area, which can benefit from the cross-fertilization of ideas in distributed systems.
