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.
