摘要
该文对卫星导航接收机中的码跟踪环路进行了研究,主要叙述了锁相环(PLL)、数字环路滤波器、延迟锁定环(DLL)的原理和实现DLL的两种方式,并对这两种实现方式作了仿真。
This paper carefully researches on code-tracking loop in satellite navigation receivers and mainly refers to the principle of phase locked loop (PLL), digital loop filter, delay-early locked loop (DLL) and the realization of DLL. The simulation of the realization on DLL is done.
