本文讨论了一种用于W CDMA MT的数字载波跟踪环路。它利用W CDMA系统的导频信号,实现了一种鉴频鉴相环路。计算机仿真结果显示该环路可以保证可靠的载波恢复。
This article discusses a digital carrier tracking loop for W CDMA MTs. It utilizes the pilot signal of W CDMA system, has realized a kind of frequency discrimination phase-locked loop. Computer simulation results show that the loop can ensure reliable carrier recovery.
