A Novel Cooperation Design for MIMO Radar-Communication Spectrum Coexistence

This paper presents a novel cooperation optimization formulation for the multiple-input multiple-output (MIMO) radar and MIMO communication system spectrum coexistence. To optimize the communication rate and the radar filtered interference power (FIP) simultaneously, the radar transmitreceive beamforming and communication codebook are jointly optimized with the constrained weighted sum design. To solve the nontrivial multi-variables problem, an alternating iteration is derived that allows to decompose the non-convex optimizations into three suitably designed sub-problems, whose solutions are provided in closed-form. Finally, numerical results are provided to illustrate the merits of the proposed approach and validate the theoretical analyses.
