摘要
研究了非扩频卫星通信系统分别工作于欠饱和状态和过饱和状态时,上行部分的干扰频带占有率对系统性能的影响,并以某一通信系统为例进行了分析,得出结论:随着干扰带宽占有率的减小,干扰效果将随之增强,但受扰信道也随之减少。
This paper studies the influence of jamming band occupancy ratio of up-links on the system performance when the non-spread spectrum satellite communication system is running in the states of under-saturation and over-saturation respectively,and analyzes it taking a certain communication system as an example,educes the conclusion that the jamming effect will increase and the channels jammed will decrease with the jamming band occupancy ratio decreases.
