摘要

多用户MIMO (MU-MIMO)下行链路中的空间复用允许系统中的每个用户使用相同的时间和频谱资源同时接收多个数据子信道。本文在最近提出的信噪比(SLNR)最大化算法的基础上，提出了一种对发射天线数和接收天线数没有严格约束的连续迭代优化方法。仿真结果表明，该方法优于原SLNR算法，在误码率性能和系统容量方面均有较大提高。

A successive iterative optimization precoding method for downlink multi-user MIMO system

Spatial multiplexing in the multi-user MIMO (MU-MIMO) downlink allows each user in the system to receive multiple data subchannels simultaneously using the same time and spectral resources. In this paper, we have proposed a successive iterative optimization method based on signal-to-leakage-and-noise-ratio (SLNR) maximization algorithm proposed recently, which has no strict constraint on transmit and receive antennas numbers. Accoding to the simulation results, the proposed method outperforms the original SLNR algorithm and have a considerable improvement in BER performance and system capacity.
