摘要
MIMO系统可有效对抗衰落并提高系统容量。在实际环境中,MIMO系统可能接收到来自空间某个方向上的干扰。针对空时分组码MIMO系统,给出一种基于MMSE准则数字波束形成的干扰抑制方案,仿真结果表明该方案能有效抑制MIMO系统中的强定向干扰,但与无干扰的理想情况相比,系统的一些性能有所降低。
MIMO communication system is an effective system to mitigate fading effect and improve system capacity.In real environments,the MIMO system may face interference coming from certain direction.This paper presents a scheme to suppress directional interference for STBC MIMO system based on MMSE beam-forming.Simulation result shows that the scheme is valid to suppress directional strong interference for STBC MIMO system although with some performance degradation compared with the ideal case of non-interference.
