Talk Title: Random Signal Processing for ISAC
Abstract: Radar systems typically employ well-designed deterministic signals for target sensing. In contrast to that, integrated sensing and communications (ISAC) systems have to adopt random signals to convey useful information, potentially causing sensing performance degradation. In this talk, we will analyze and optimize the ISAC performance relying on random signaling over multi-antenna and multi-carrier systems, where we propose dedicated precoding design and probabilistic constellation shaping approaches to improve the sensing performance while guaranteeing the communication QoS. Despite their computational complexities, we will show that the proposed methods are able to be implemented offline, and are thus readily applicable to practical 6G ISAC applications.
