Abstract

This page hosts the extended version of the paper, including detailed appendices and proofs omitted from the conference version due to space limitations. The paper develops a Fisher-information-based analytical framework for evaluating sensing accuracy in ISAC cell-free massive MIMO systems and derives closed-form CRLB expressions for channel-gain and angle-of-arrival estimation.
