本文讨论了推导一对天线单元在基站的相关系数的封闭形式的表达式。封闭形式的表达式推导出的情况下，一个多模态截断拉普拉斯功率方位角频谱的影响，展示了一个方向性的辐射模式，被广泛用于标准化机构的天线元件。为了避免数值不稳定性，提出了一种小方位角扩展的近似方法。建议的封闭形式的表达，沿着其近似，成功地验证了对相关系数的数值计算。
This paper addresses the derivation of a closed-form expression for the correlation coefficient of a pair of antenna elements at the base station. The closed-form expression is derived for the case of a multimodal truncated Laplacian power azimuth spectrum that impinges on antenna elements exhibiting a directive radiation pattern that is widely used in standardization bodies. To avoid numerical instability, an approximation for small azimuth spreads is presented. The proposed closed-form expression, along with its approximation, is successfully validated against the numerical computation of the correlation coefficient.
