基于宏小区及微小区MIMO信道模型，比较了MIMO信道在两种传输环境中的空间相关特性，通过数值分

析方法得到了两类信道空间相关性随发送端、接收端天线阵列的分布而变化的特征曲线，并分析比较了信道参数，

即到达角的角度扩展，对空间相关性的影响。-The space correlation is analyzed in different propagation conditions including the MIMO macro-cell and

micro-cell applications. The characteristics curves describing the space correlation versus the distance of antennas

are obtained according to the numerical analysis. The effect of the spread of the angle of arrival on the space

correlation is also investigated.
