【摘要】The generalized 3-D scattering model for microcell environment is investigated, and MS( mobile station) located inside the 3-D scattering semi-spheroid and BS ( base station) employing a directional antenna at the center of the semi-spheroid is idealized. The joint probability density functions ( pdfs) and marginal pdfs of AOA and TOA seen at BS and MS in correspondence with azimuth and elevation angles are derived by using a simple approach, and all formula results are in explicit closed-form expressions. Comparisons between the theoretical calculations and customary 2-D results show that these analyses are correct and applicable to microcell environment. And this could promote the research of statistical channel models.%针对在均匀散射体分布以及空间对称的3-D室内移动通信环境,细化了对于基站( BS,Base Station)以及移动台( MS,Mobile Station)端空间角度的研究。对在指向性天线覆盖下的室内微小区移动通信环境下,模型能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竖直平面上的信号到达角度( AOA,Angle of Arrival)以及到达时间( TOA,Time Of Arrival)。数值仿真结果与2-D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3-D空间统计信道模型的研究和应用。
