Joint Transmit Design with Interference Management for Radar and Communication Coexistence System

In this paper, we propose a new high-performance spectrum sharing configuration method for radar communication spectrum coexistence system. The controlled degrees of freedom are the transmit matrix of communication system and radar transmit vector. In order to maximize the signal to interference noise ratio (SINR) under the conditions of transmission energy, the similarity of radar and radar reference transmit vector, and achievable communication system rate constraints, this paper presents a new algorithm based on the derived local design, which is less computationally complex than the traditional alternating convex transform method. Numerical results demonstrate the advantages of the solution proposed in this paper.
