摘要

我们考虑了蜂窝通信系统中空间干扰方向图变化所产生的信噪比变化，这种变化在使用自适应阵列进行传输时尤为严重。在本文中，我们推导了干扰抑制组合(IRC)和最大比组合(MRC)接收机在等功率干扰条件下的输出SINR变化分布。该分析可用于评估系统级SINR变化。结果表明，IRC在蜂窝网络中较窄的天线波束宽度下具有较好的信噪比和信噪比变化特性。

Characterization of SINR uncertainty due to spatial interference variation

We consider the SINR variation generated by the change of spatial interference pattern in a cellular communication system, which is especially severe when using adaptive array for transmission. In this paper, we derive the distribution of SINR variation at the output of Interference Rejection Combining (IRC) and Maximum Ratio Combining (MRC) receivers, assuming equal-power interferers. The analysis can be applied to evaluate a system level SINR variation. According to the results, we found that IRC shows better SINR and SINR variation properties under a narrow antenna beamwidth practical in cellular networks.
