| 摘 要： | 扩频测控系统以其诸多优点正成为卫星测控的主流体制,经典分析给出扩频系统的干扰容限只是一个宽泛的界。在同时考虑输入信号强度、多址干扰等因素的情况下,对扩频测控系统的干扰容限上界进行分析推导,得出更符合实际情况的干扰容限上界的闭式表达,通过计算给出干扰容限与多址干扰、干扰容限与输入信噪比强度的关系。

| Abstract: | Due to the advantages of spread spectrum TT&C system,it is becoming the mainstream TT&C system.The loose bound of jamming threshold for spread spectrum system has been already given in traditional analysis.While in this paper,considering different input SNR levels and different multi-user interferences simultaneously,the close form of a tight jamming threshold for spread spectrum TT&C system is deduced.Calculation results of the relations of jamming threshold vs.multi-user interferences and input SNR levels... |
