When Do Pilots Matter for OFDM Sensing? Pilot-Data Resource Design for ISAC
An analytical and optimization framework for pilot-data (P-D) OFDM sensing is established and when and how pilot placement can be exploited to regulate the sensing behavior of random OFDM communication signals is revealed, providing practical resource-design principles for OFDM-based ISAC.
