To reduce the negative impact of channel quantization errors.a low-complexity transceiver joint design scheme for both the transmit beamformers and receive combining vectors is proposed in the two-user multiple-input multiple-output (MIMO) system.In the scheme,the channel nullspace quantization vector is used as the transmit beamformer of the interference user directly based on channel null-space feedback.Since the interference can be determined at the receiver,interference rejection combining ( IRC ) is jointly utilized to cancel the inter-user interference.Simulation results show that the proposed scheme can provide substantial sum-rate improvement especially at high SNR.
