Fundamental Limits of Communication-Assisted Sensing in Integrated Sensing and Communication Systems
The core message of this paper is to establish a novel communication-assisted sensing (CAS) system framework that enables users to sense device-free targets beyond line of sight, and to characterize the fundamental limits of achievable sensing distortion at the user end within this CAS framework.
Cooperative Sensing and Communication in Integrated Sensing and Communication (ISAC) Networks: Performance Analysis and Optimization
The core message of this article is to propose a cooperative ISAC network framework that integrates coordinated multi-point (CoMP) joint transmission and distributed radar techniques to enhance both sensing and communication (S&C) performance at the network level. The authors analyze the S&C performance through the data rate and Cramér-Rao lower bound (CRLB), and apply stochastic geometry techniques to derive key insights on the scaling law of localization accuracy and the optimal cooperative cluster size.
