微蜂窝多径衰落信道中的无线电信号传播模式

Propagation Model of Radio Signal in Microcellular Multipath Fading Channel

城市移动传播信道是一种典型的随机色散的变参信道，在对城市微蜂窝移动通信网进行规划设计时应充分了解这种信道的传播特性，并建立相应的信号传播模型。在分析了微蜂窝多径衰落信道信号传播形式的基础上，对信号传播系数及信号功率在信道中的传播分布模式进行了研究，从而为深入研究移动通信中的信号与干扰传播理论提供了一定的基础。

Urban mobile propagation channel is a typical random dispersive parametric variation channel, so it is necessary to study the propagation property of the channel and build the signal propagation model in the process of planing and designing urban microcellular mobile communication networks. Based on analysing the signal propagation pattern in microcellular multipath fading channel, this paper studied the signal propagation coefficient and propagation distribution model of signal power in the channel, which provided given bases for deeply researching the propagation theory of signal and interference in mobile communication.
