摘　　要：A robust design for Generalized vector precoding （GVP） is proposed in multi-user Multiple input multiple output （MIMO） downlink system. When the transmitter has imperfect Channel state information （CSI） due to channel estimation errors, the optimum perturbation vector and precoding matrix are derived based on Minimizing mean square error （MMSE） criterion by use of statis Acal information of channel errors. Simulation results show that the proposed precoder is more robust to imperfect CSI than conventional precoders.
