摘要
文章在对信号的捕获方法进行了研究的基础上,将展开对扩频信号跟踪方法的研究与设计。通过对锁相环的基本原理进行阐述,采用两种特殊的锁相环——DLL和Costas环分别实现伪码跟踪环路和载波跟踪环路的设计。
On the basis of doing research on the problem of signal capturing, This paper designs method of following track of spread frequency signal, the problems of PLL are analyzed and the theoretic are presented, In the end, Pseudo-code Tracking Loop and Carrier Wave Tracking Loop are implemented by DLL and Costas Loop separated.
