摘要
城市微蜂窝移动无线电信道的传播特性相当复杂，因此如何建立这种信道的传播模型无论对理论分析还是对网络工程应用来说都是非常重要的．本文在分析讨论多径色散信道基本特征的基础上，对反映城市微蜂窝移动无线电信道传播特性的一些重要特征函数的数学模型进行了较为系统的分析和研究，并对一些重要模型进行了计算机仿真．
It is important to build the propagation model of urban microcellular mobile radio channel, since its propagation properties are complicated for either therorical analysis or engineering application. In this paper based on the discussion of basic characteristics of multipath dispersive channel, the mathematics models of some important characteristic functions which can express the propagation properties of urban microcellular mobile radio channel are analyzed systematically. The performances of some important channel models are simulated also.
