摘要
文章分析了地球站在干扰情况下系统误码率计算方法,谈论了卫星通信中主要的干扰信号样式,并给出了几种常见干扰信号的表达式和功率谱密度,然后利用MATLAB/Simulink建立了卫星通信干扰模型,分别仿真了单音信号,多音信号和脉冲信号干扰地球站接收系统。通过仿真分析,得到了三种干扰信号对地球站的干扰效果,对地球站抗干扰具有指导意义。
The performance of earth station under interference is analyzed.When discussing variety interference signals,several common interferences＇ signals and spectrum density expression is given.Then earth station simulation mode with interference is built with MATLAB/Simulink.Simulated earth station performance under tone signal、multi-tone signal and pulse signal interference.By analyzing the simulation results,the jamming effects of the three interference signals are obtained.It＇s valuable for anti-jamming of earth station.
