Efficient Transmit and Receive Optimization Design for Multiuser Spatial Multiplexing Systems

摘要：

The multi-antenna system can significantly increase the spectral efficiency of wireless systems.This paper proposes a novel low complexity preprocessing scheme for multiuser multiple-input multiple-output (MUMIMO) system.The proposed precoding algorithm decomposes the composite downlink channel into the multiple sub-channels without inter-user interference and has lower cost than traditional algorithms.At the same time,an efficient equalization algorithm is proposed to achieve the joint optimal design in receiver.Simulation results show the feasibility and effectiveness of the proposed algorithm.
