| 摘 要： | 针对符合多簇拉普拉斯分布的功率角度谱，推导了适用于均匀线阵和均匀圆阵信道相关性的闭式表达式. 该表达式反映了信道角度功率谱以及交叉极化鉴别率对信道相关性的影响. 比较了具有相同角度扩展的单簇与多簇拉普拉斯角度功率谱引入信道相关性的差异. 分析了簇内角度扩展不同时，天线阵列信道相关性随均匀线阵天线间距或均匀圆阵半径的变化. 给出了簇内平均角和簇内角度扩展分别取不同值时，信道交叉极化鉴别率对应的等效天线间距.

| Abstract: | Regarding to the multi-cluster Laplacian power azimuth spectrum ( PAS) ,a closed-form expression for the channel correlation applicable to the uniform linear array ( ULA) and uniform circular array ( UCA) is derived. Both the PAS and cross-polarization discrimination ( XPD) are taken into consideration. The channel correlation values introduced by the single-and multi-cluster Laplacian distribution with the same angular spread( AS) are compared. The channel correlation as a function of the antenna spacing o... |
