Abstract

This article consists of a collection of slides from the author's conference presentation. We design a power efficient optimization-based beamforming technique for the coexistence of MIMO radar and downlink MU-MISO communication based on exploiting the constructive interference power, where two optimization problems are formulated: a) Power minimization and b) Interference minimization. We develop an efficient gradient projection algorithm for the power minimization problem. We analytically derive the detection probability for MIMO radar when the proposed beamforming scheme is used. Numerical simulations show that the proposed approach outperforms the conventional SDR-based method significantly.
