摘要
提出了三维(Three Dimension,3D)信道模型下的新型的同心圆天线阵列模型,数值推导该模型的空间相关性与扩展方位角(Azimuth Spread,AS)和俯仰角(Elevation Spread,ES),平均中心到达方位角(Mean Azimuth of Arrival,MAOA)和俯仰角(Mean Elevation of Arrival,MEOA)的函数关系式,通过MATLAB数值仿真,比较不同阵元位置以及不同的空间到达角度对于线性(Uniform Liner Array,ULA)阵列,圆形(Uniform Circular Array,UCA)阵列以及提出的新型同心圆天线阵列结构的空间相关性分布情况,从而验证提出的天线阵列结构具有优越的高容量的性能,进而推动无线通信领域的研究与发展。
A new digital uniform concentric circular array in a three-dimensional spatial channel model is proposed in this paper, and the general spatial correlation expressions of channel model with the impact of azimuth spread and elevation spread, mean azimuth of arrival and mean elevation of arrival are derived. Comparisons among the uniform linear array, uniform circular array and the uniform concentric circular array show the ideal performance of uniform concentric circular array, that promotes the research of the statistical channel models.
