同步跟踪则由多径跟踪的结果精确估计PN序列码相位，并实时跟踪信道各径成分由于多普勒效应产生的时延漂移。

Following, code tracking confirm the PN code phase precisely and track every multipath component's delay drifting due to Doppler effect.

基于非相关早减迟延时锁定环和反正切载波跟踪环，得出了由一般形式的误差解析表达式导出的码相和载波相位跟踪误差曲线。

Based on noncoherent DLL and arctan carrier PLL, the curves of tracking errors in general forms are given after a series of computing and simulation.

跟踪阶段，分析了同相码跟踪环的特点，然后根据其不足之处，选择同相正交码环来对码相位进行跟踪。

At tracking stage, after analysis the characteristics of the In-phase code tracking loop, the paper USES the In-phase and Quadrature code tracking loop to track the code phase.
