摘要(Abstract)：
为了更准确的分析三维空间(three-dimensional,3D)信号的链路损耗,本文建立了一种均匀矩形阵列(Uniform rectangular array,URA)的三维统计信道模型;给出了三维多径信道在均匀矩形阵列下的空间衰落相关函数封闭形式表达式.该式表明衰落相关函数与到达方位角(arrival of angle,AOA)、到达仰角(elevation of angle,EOA)及均匀阵列与天线之间距离和几何形状有关.计算机模拟仿真结果和理论结果吻合,方位扩展角(Azimuth spread,AS)是影响天线相关性的主要因素.本文最后的结论可以用在分析多输入多输出(Multipleinput multiple-output,MIMO)系统的容量,优化信道链路损耗模型,拓展天线阵列灵敏度的研究分析.
