Abstract

Co-existence of radar and communication systems based on cooperative spectrum sharing is of significant interest in recent years. This letter proposes two joint power allocation schemes for radar and communication spectrum sharing, where both systems use the same bandwidth with cross interference between them. The proposed joint design maximizes a performance metric of one system while meeting a service constraint requirement for the other, i.e., throughput for the communication system or signal-To-interference-plus-noise ratio (SINR) for the radar. For both designs, we show that either the radar or the communication system needs to transmit at peak power to achieve the optimum solution, depending on the relation among the peak power constraint, channel conditions, and service constraints.
