同步轨道邻星干扰分析

文中主要研究了邻星干扰对卫星通信系统的影响。建立了一个邻星干扰的系统模型，推导了通信链路的误码率性能与有用信号信噪比、干扰信号信噪比、链路夹角和系统中断率的关系。并利用ITU雨衰预测模型以及地球站所在地区的雨衰数据，分析了各因素对我国上空两颗邻星的影响。仿真结果得到了一些比较有参考价值的数据及结论，这些结论可以为卫星通信系统干扰协调提供参考。

Analysis of Adjacent Satellite Interference of Geostationary Orbit

This paper mainly studies the performance of satellite link suffering from the adjacent satellite interference （ASI） and rain attenuation. We establish an adjacent satellite interference system model,de- duce the relationship between the bit error percentage （BEP） and the ratio of signal to noise ,the ratio of interference signal to noise, link angle and system interrupt rate. At the same time, this article analyzes the effects of two adjacent satellites in china caused by different factors by using the models of ITU rain atten- uation prediction, as well as the rain attenuation data of the earth station regions. Some data and conclu- sions obtained from the simulation provide reference for the interference coordination of the satellite com- munication systems.
