Over-the-Air Time-Frequency Synchronization in Distributed ISAC Systems
We analyze the Cramer-Rao bounds (CRBs) for TO and CFO estimates and evaluate the impact of D-ISAC synchronization on the bottom-line target localization performance.
Signaling Design for Noncoherent Distributed Integrated Sensing and Communication Systems
The ultimate goal of enabling sensing through the cellular network is to obtain coordinated sensing of an unprecedented scale, through distributed integrated sensing and communication (D-ISAC).
