摘要
从多径色散信道的特征分析出发,采用菲涅耳区原理和射线方法建立起了城市微区多径散射环境中移动无线信道的等效物理模型,并在此基础上对移动无线电波的传播特性及其作为传播模型特征参数的电波传播系数进行了分析研究。
Having analyzed the characteristics of multipath dispersive channel, the paper built up the equivalent physical model of mobi1e radio channel in urban microcellular multipath scatteting envi-ronment with the help of Fresnel theory and the ray method. Based on this, the propagation proper-ties of mobile radio wave as well as the wave propagation parameter have been analyzed and studied.
