摘要： 建立三维接收天线阵列的空间信道模型，将以往的信道建模方向推广到空间域，给出该信道模型的通用数学表达式。针对该通用形式，将来波信号角度描述扩展到俯仰角和方位角，推导该信道模型下空域相关系数的数学表达式，显示接收天线阵的形状对空域相关系数的影响。分析当来波信号的功率谱(俯仰角和方位角)分别为均匀、高斯、拉普拉斯分布时的空域相关系数，给出了数值仿真结果。

Abstract: Three-dimensional antenna array channel model is set up in this article. The channel model setting is extended to space. The general mathematics expression of channel model is given. According to the 3-D antenna array, the describing of the arrival angle is extended to pitching angle and azimuth angle. The spatial correlation based on this channel model is given too. The relation between the antenna array and the spatial correlation is showed. The correlations with the uniform, Gaussian and Laplacian power azimuth spectrum distributions are derived in this article. The computer simulations are given.

Key words: MIMO system, correlation coefficient, angle spread, Direction Of Arrival(DOA), channel model
