摘要

本文根据移动通信中电波传播的基本特点

推导出以地形特征及传播特征为参数的多径传播时延的分布密度。这一分布密度与目前公认的指数分布不同

但将它作为一种特殊情况包括在内。文中给出了时延服从指数分布的条件

并较圆满地解释了试验中观察到的一些现象。最后讨论了分布密度公式中两个参数的物理意义。

Abstract

According to the basic character of mobile radio propagation

a distribution density of multipath propagation delay containing two parameters with characteristics of terrain and propagation is derived. The distribution density differs from the exponent’s but can be degraded into the exponent distribution by choosing a specific parameter value. The conditions under which the time delay takes on the exponent distribution are given. Some of the observed results in experiments are explained. Finally

the significance of the two parameters in the distribution density is discussed.
