Joint Beamforming Scheme with Low Complexity for Multiuser MIMO System
摘要
Abstract
A joint beamforming scheme is presented for multiuser multiple-input multiple-output (MIMO) system with limited feedback. The proposed scheme uses per-user unitary rate control (PU2RC) at the transmitter and the signal-to-interferenle-plus-noise-ratio (SINR)-maximization-based antenna combining algorithm at the receiver, which searchs optimal receive combiner by using a generalized Rayleigh-Ritz method. Simulation results show that the scheme makes full use of channel information and improves the performance of the conventional PU2RC system. It outperforms the zero forcing (ZF) joint beamforming schemes in terms of sensitivity to the channel state information (CSI) quantization error, complexity of user selection, and sum rate in the case of low feedback rate conditions.关键词
