摘　　要：为提高无线通信系统的性能,针对大多数模型忽略了信号传播的三维特征和计算复杂的问题,提出一种适合室外宏小区环境的三维几何散射模型。在宏小区上行移动通信环境下,分析在基站空间到达角的统计特性,推导多径分量到达角的概率密度函数表达式。将其仿真结果与其它文献提出的2D和3D模型的多径分量到达角概率密度函数数值结果相比较,比较结果表明,该模型准确有效,计算成本较低,扩展了3D空间信道模型的研究和应用。To improve the performance of the wireless communication system and to solve problems of most models ignoring three-dimensional characteristics of the signal transmission and computing intricately,a three-dimensional geometric scattering model applied to macrocell outdoor area was proposed.In the macrocell uplink mobile communication environment,statistics of arrival angle at the base station were analyzed and the probability distribution density function of the arrival angle of multipath components of the model was deduced.Comparing with numerical results of the probability density function of multipath component of 2Dand 3D models proposed in other literatures,this model is accurate and effective and its computational cost is low,which expands the research and application of 3Dspatial channel model.
