Abstract

RF convergence where the same transceiver is used for communications and sensing purposes is taking place. In this paper, a dual-use radar-communications multicarrier waveform is proposed, where different subcarriers are assigned to different subsystems. Two algorithms for subcarrier assignment and optimal power allocation for the radar and communications subsystems are developed. A compound mutual information (MI) based objective function is used for optimizing the power allocation of each subsystem in both design algorithms. The first proposed design algorithm assumes priority for the radar subsystem and it is called radar selfish design. The second proposed design algorithm is called cooperative design, in which both subsystems are jointly optimized by maximizing a compound MI based objective function.
