GS-16QAM OFDM with ANN scheme combined with LFM signal for joint communication and radar sensing system
Abstract:
In this Letter, an integrated waveform geometrically shaped (GS) 16 quadrature amplitude modulation (QAM) based orthogonal frequency division multiplexing (OFDM) communication signal combined with a linear frequency modulation (LFM) radar signal is proposed and experimentally demonstrated in a W-band communication and radar detection system. The proposed method can generate communication and radar signals simultaneously. The inherent error propagation and the interference of the radar signal limit the transmission performance of the joint communication and radar sensing system. Thus, an artificial neural network (ANN) scheme is proposed for the GS-16QAM OFDM signal. After 0.8-m wireless transmission, the experimental results show that the receiver sensitivity and normalized general mutual information (NGMI) of the GS-16QAM OFDM are improved compared with that of the OFDM with uniform 16QAM at the forward error correction (FEC) threshold of 3.8 × 10-3. In addition, multi-target radar detection in centimeter level radar ranging is realized.
