| 摘 要： | 本文提出了大卫星定位通信系统中采用四相扩频（Ｑ－ＳＳ）技术，并沿用瑞士人给出的卫星转发器功率放大器的数学模型，推导了Ｑ－ＳＳ信号通过卫星转发器后输出的表示式；通过进一步分析发现了采用Ｑ－ＳＳ技术可以在信号解扩后完全消除三阶和五阶的互调干扰。

| Abstract: | This paper puts forward the application of a Quadri phase spread spectrum (Q SS) technique in the system of satellite position and communication, adopts a model of satellite transponder which is given by Swiss, and deduces Q SS expressions at the output of satellite transponder. By further analysis, it is discovered that Q SS technique can completely eliminate the third and the fifth intermodulation interference. |
