It is well known that OFDM-based systems are susceptible and weak towards subcarrier misalignment, which can lead to erroneous demodulation of the receive signal. In the usage of OFDM Radar-Communication systems, whether within cooperative or non-cooperative networks, non-overlapping subcarriers are assigned to all RadCom nodes in the vicinity. Even so OFDM subcarrier misalignment can still arise from Doppler and hardware carrier frequency offset, which lead to inter-system interference… CONTINUE READING
