摘要： 根据微小区双散射的MIMO椭圆信道模型，分析发送、接收端阵元天线间的信道相关性，考虑到发射端与接收端周围存在大量散射体，且散射体服从非均匀分布，采用Von Mises分布函数描述散射角度的分布情况，从而得到信道相关函数的闭式表达式，并通过仿真分析影响信道相关性的主要因素。实验结果表明，相关系数随天线间距、角度扩展、扩展因子的增大而非单调性减小，为MIMO技术的应用提供了有效理论依据。

Abstract: Two-scattering elliptical Multiple Input and Multiple Output(MIMO) channel model is established for micro-cell. The channel correlation characteristic between sending and receiving element antenna is analyzed. On considering the existence of a lot of scattering bodies, which is of non-uniform distribution, around the transmitter and receiver, the closed expression type of channel correlation function is obtained describing the distribution of scattering angle by Von Mises distribution function. The main factors affecting channel correlation characteristic is analyzed. Experimental results show the correlation coefficients reduces non-monotoniclly with the increase of antenna distance, angle expansion and expansion factor, which provides efficient theoretical base for the application of MIMO system.
