Topic:Flowing the Information from Shannon to Fisher: Towards the Fundamental Tradeoff in ISAC
Speaker: Fan Liu (Assistant Professor, Southern University of Science and Technology)
Time: 10:30 (Friday), August 26, 2022
Venue: Research Building Block B, 302 (KB302)
Host: Professor Qian He
Introduction:
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 shall provide a general framework to reveal the fundamental tradeoff between sensing and communications (S&C), where a unified ISAC signal is exploited to perform dual-functional tasks. In particular, we define the Cramér-Rao bound (CRB)-rate region to characterize the S&C tradeoff, and propose a pentagon inner bound of the region. We show that the two corner points of the CRB-rate region can be achieved by the conventional Gaussian signaling and a novel strategy corresponding to the uniform distribution over the Stiefel manifold, respectively. Moreover, we also offer our insights into transmission approaches achieving the boundary of the CRB-rate region, namely the Shannon-Fisher information flow.
