报告一题目：On the Fundamental Tradeoff of Integrated Sensing and Communications Under Gaussian Channels

主讲人：Fan Liu

摘要：Integrated Sensing and Communication (ISAC) is recognized as a promising technology for both the next-generation wireless networks and radar systems. In this talk, we consider a P2P ISAC model under vector Gaussian channels, and propose to use the CRB-rate region as a basic tool for depicting the fundamental sensing and communications (S&C) tradeoff. We characterize the S&C performance at the two corner points of the CRB-rate region. In particular, we derive the high-SNR communication capacity at the sensing-optimal point, and provide lower and upper bounds for the sensing CRB at the communication-optimal point.
