【 摘 要 】

The stable and reliable tracking of the captured signal is the precondition for successfully demodulating the signal. Therefore, the realization of the tracking loop software processing becomes one of the key issues in the software processing of the spread spectrum signal. This paper analyzes the basic principles of PLL, code loop and carrier loop, and gives their software implementation methods, which lays a good foundation for the tracking of spread spectrum signals.
