Fundamental CRB-Rate Trade-Off in ISAC Systems Under Correlated Communication-Sensing Channel

Integrated sensing and communication (ISAC) has been esteemed as a pivotal driver for the next-generation wireless networks in achieving dual-function spectrum efficiency. In typical ISAC systems, user equipment and targets are treated as distinct entities, operating without interaction between the...
