针对散射体均匀分布以及三维空间域（3 dimension，3D）移动通信环境，提出了3D空间统计信道模型. 对在指向性天线覆盖下的室内微小区移动通信环境，模型能够估计多径衰落信道的重要空时信道参数，如波达信号在水平面以及垂直面的信号到达角度（angle of arrival，AOA）以及多普勒效应（Doppler spectra，DS）等. 移动台（mobile station，MS）的移动特性会使接收信号产生多普勒效应，根据运动的相对性理论，基站（base station，BS）也会有相对运动，因此也会有多普勒效应产生. 本文引入控制变量法导出三维空间域在MS以及BS 端的多普勒效应，数值仿真结果与室外3D多径衰落信道对比表明，本模型的信道参数估计结果符合理论和经验，扩展了3D空间统计信道模型的研究和应用.

In this paper we investigate a generalized three-dimensional (3D) scattering channel model for microcell environments, which idealizes a directional antenna at the center of the semi-spheroid. The joint and marginal PDFs of angle of arrival and Doppler spectra are derived. According to the theory of the relative motion, with the movement at the mobile station, the base station is relatively moving, which will also produce Doppler spectra. Comparisons between our theoretical calculations and customary 3D results show that the analyses are correct and applicable to microcell environments, which promotes the research of the 3D scattering channel models.[1] Ertel R B, Reed J H 1999 IEEE J.
