Joint Design for Communication Beamforming and Radar Waveform in MIMO Radar and MU-MIMO Communication Co-Existing System

This paper considers a joint design for communication beamforming matrices and radar waveform in a scenario where a multiple-input multiple-output (MIMO) radar and a MIMO communication system coexist. We propose a joint optimizing method to maximize the sum rate by designing the communication beamforming matrices and the radar waveform. We give consideration to power constraints for both radar and communication system. In order to guarantee the radar performance, we also consider the similarity constraint of the radar waveform. This paper formulates two convex optimization problems and proposes an alternating iterative algorithm. Finally, the simulation results verify that the proposed algorithm can effectively raise the sum rate.
