The authors propose a co-design framework for a statistical (widely distributed) MIMO radar and an in-band full-duplex (IBFD) multi-user MIMO (MU-MIMO) communications system that operate concurrently within the same frequency band. The proposed approach jointly optimizes the radar waveform, communications precoders, and receive filters to maximize a compound weighted sum mutual information (CWSM) metric, while accounting for practical constraints such as transmit power limits, quality-of-service requirements, and peak-to-average-power ratio.
This paper proposes a comprehensive framework for co-designing distributed MIMO radar and in-band full-duplex multi-user MIMO communications, addressing multi-target detection, localization, and tracking.
