摘要

卫星无线信道仿真是卫星移动通信的必要工作.文章归纳卫星通信典型的大尺度衰落、小尺度衰落特性,同时介绍高斯白噪声滤波法、Rayleigh信道建模、Rician信道建模等基于卫星统计信道建模方法.针对低轨卫星星信道冲击响应庞大的数据,通过数据拆分,降低数据处理的难度.

Abstract

Satellite wireless channel simulation is a necessary task for satellite mobile communication. This article summarizes the typical characteristics of large-scale fading and small-scale fading in satellite communication,and introduces satellite statistical channel modeling methods such as Gaussian white noise filtering,Rayleigh channel modeling,Rician channel modeling,etc. In response to the massive data of impulse response in low Earth orbit satellite channels,data splitting has been used to reduce the difficulty of data processing.
