关于移动信道分析模型的研究

移动信道特性的研究是移动通信系统研究领域中最重要的部分，也是近年来研究的热点之一。其中多径传播和阴影效应是信道的主要特点，几乎任何统计特性都建立在此基础上。主要是介绍一种移动信道的分析模型，该模型的地理环境为市区，即移动台和基站之间不存在直视波（LOS），并从多普勒功率谱的角度给出了接受信号振幅和相位的概率密度函数（PDF）盈自相关和互相关函数。

Research on mobile channel analysis model

The analysis of the mobile channel's attribute is an important part in the research field of mobile communication system.It becomes a hot topic these years.The major characteristics of channel are multipath transmission and shadow effect.Nearly all statistic attributes are based on these characteristics.The paper introduces an analysis model for mobile channel,whose geographic environment is town center,which means there is no LOS among the mobile station and the basis station.And the paper states the accepted signal swing,the phasic density function(PDF),the self-related and co-related functions.
