摘要
利用陆地移动卫星信道中电波分量的分布特点,推导出了全阴影环境下地面接收信号的多普勒功率谱密度的最新表达式和曲线,并与理想环境下的结果作比较分析,深刻而直观地揭示出了二者的差异.
Using the distribution properties of the components of the electric waves in land mobile satellite channels,it is deduced the newest expression and curve for the Doppler power spectral density of the received signals on land surface in complete shadowing environment.The comparison between these results and those in ideal enviroment shows their differences deeply and obviously.
