Robust Optimization of Linear Precoders/Decoders for Multiuser MIMO Downlink with Imperfect CSI at Base Station

A robust scheme is proposed to optimize the linear precoders/decoders for MIMO downlinks where the available channel state information (CSI) at base station (BS) is imperfect. The objective is to minimize the sum mean square error (SMSE) over all data sub-streams under a per-user transmit power cons...
