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

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。

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.
