OFDM based Waveform Design and Digital Beamforming Technique for RADCOM System

The utilization of orthogonal frequency division multiplexing (OFDM) in wireless communication systems has become widely popular due to its effectiveness in mitigating frequency selective fading and enhancing spectral efficiency. This study introduces a RADCOM (Radar Communication) system utilizing OFDM, incorporating digital beamforming to enhance its performance. Through simulation results, the proposed system surpasses conventional OFDM-based RADCOM systems in terms of bit error rate (BER) and signalto-noise ratio (SNR) across various distances by amplifying the SNR of received signals. Moreover, it demonstrates superior resistance to multi-path fading and interference, suggesting its applicability in diverse RADCOM scenarios.
