摘要
本文探讨了直扩信号的检测与参数提取的原理，提出了利用信号的隐周期特征获得直扩信号的载频、扩频时钟、扩频码周期、扩频码序列的方法，并仔细推导了各种方法的性能．
This paper discussed the principle of DS signal detection and parameters extraction Some methods were developed for extracting the carrier of DS signal ,rate of spread code,periods of spread sequence and spread sequence The performances of these methods were also discussed in detail.
