Query: Robust MIMO Beamforming for Cellular and Radar Coexistence   In this letter, we consider the coexistence and spectrum sharing between
downlink multi-user multiple-input-multiple-output (MU-MIMO) communication and
a MIMO radar. For a given performance requirement of the downlink communication
system, we design the transmit beamforming such that the detection probability
of the radar is maximized. While the original optimization problem is
non-convex, we exploit the monotonically increasing relationship of the
detection probability with the non-centrality parameter of the resulting
probability distribution to obtain a convex lower-bound optimization. The
proposed beamformer is designed to be robust to imperfect channel state
information (CSI). Simulation results verify that the proposed approach
facilitates the coexistence between radar and communication links, and
illustrates a scalable trade-off between the two systems' performance.
