24 GHz QAM-FBMC Radar with Communication System (RadCom)

At the present time many studies have been carried out to jointly use the OFDM signal for communication and radar functions, but other waveforms have been shown to be better candidates than OFDM for communications applications. Therefore studies on evaluation of the application of these same signals to radar functions may be necessary. In this paper, we adapted the radar processing of the OFDM signal to be applied in a new Filter Bank Multicarrier (FBMC) scheme, which is shown to be much superior to the OFDM system since it presents the same bit error rate (BER) performance in multipath channels, a much higher spectral efficiency and as shown here, better performance in radar targeting. We evaluated its performance for radar applications with joint communications.
