摘要

本文阐述了DTTL全数字符号定时恢复算法在8PSK解调系统中的实现。文中结合8PSK解调系统

对DTTL算法中插值器、定时误差检测器、环路滤波器以及数控振荡器等进行了详细的分析。系统仿真显示了该算法稳定的跟踪性能。

Abstract

This paper presents the implement of the all-digital symbol timing recovery using the DTTL Algorithm over 8PSK demodulation system. Incorporating 8PSK. demodulation system

Interpolator

Timing Error Detector

Loop Filter and Numerically Controlled Oscillator in DTTL Algorithm are analyzed in detail. System simulation shows the stable tracking Performance of DTTL Algorithm.
