A Novel Preprocessing Scheme for Multiuser Downlink Spatial Multiplexing MIMO System
This paper proposes a combined inter-user interference minimization scheme for multiuser multi-input multi-output (MU-MIMO) system. For transmit antenna number is small, the proposed scheme improves the signal-to-interferenceplus-noise (SINR) based on a modified SLNR approach. When the constraint is free, the proposed scheme is able to force the multiuser interference (MUI) to zero at each user. The proposed algorithm achieves good bit error rate (BER) performance, has low complexity, and is suitable for practical system. Simulation results show the feasibility and effectiveness of the proposed precoding algorithm.
