Abstract

Phase-modulated continuous waveform (PMCW) has attracted wide attention for integrated sensing and communications (ISAC). Aiming at the drawback of limited communications spectrum efficiency, a code-orthogonal PMCW (CO-PMCW) transmission scheme was proposed, which improves the data rate by the simultaneous transmission of radar and communication signals while raising the problem of mutual interference (MI) between them. This paper introduces the design strategy of the CO-PMCW-based multiple-input and multiple-output (MIMO) ISAC system with customized digital beamforming for MI suppression. The simulation results demonstrate the applicability of the designed system and its merits and demerits compared to PMCW.
