FD-ISAC Processing

Compared to the traditional TDD mode, the FD mode is more suitable for ISAC systems since it allows simultaneous transmission and reception of signals (including both echoes and communication signals). Under the FD-ISAC framework, a completely new receiver signal flow needs to be designed to handle complex receiver signals. In FD-IBFD, the processing for communication signals is the same as the FD chapter process, and the radar echo signal is regarded as the self-interference signal for elimination. While the separation of the echo signal from the self-interference signal is the key to realize the accurate reception and processing of the sensed signal. And then the extracted echo signals are then subjected to signal processing to obtain sensing information.
