摘要
本文讨论跟踪与数据中继卫星系统 (TDRSS)一种新通信体制 ,即并行MSK扩频系统。发射端采用长短码正交扩频的平衡调制 ,接收端采用一种简单解扩方式简化了并行MSK信号的解调 ,同时用短码全“1”引导长码同步的方法大大减小了长码的捕获时间。实验结果证明该体制具有良好的伪码同步性能。
A novel spread-spectrum scheme for Tracking and Data Relay Satellite System(TDRSS)parallel MSK spread-spectrum modulation is discussed in this paper. A long code and a short code spread-spectrum modulation is used in the transmitter, and meanwhile an easy dispreading scheme is used in the receiver. A good synchronization property is proved by the experimental results.
