Symbol-Level Precoding for Minimizing Ranging CRB in ISAC Systems: A Low-Complexity Approach
This letter investigates a dual-functional waveform design for MIMO-OFDM integrated sensing and communication (ISAC) systems. Firstly, an optimization problem of minimizing the radar ranging Cramér-Rao bound (CRB) is formulated under the constraints of multi-user communication quality of service (QoS) and transmit powe...
