摘要

本文提出了在相位量化下的高精度定时综合理论，并基于Ｖｉｔｅｒｂｉ算法提出了一种最优合成方法．同时，还给出了基于ＴＶｉｔｅｒｂｉ的简化方法并对ＴＶｉｔｅｒｂｉ和二阶ＳｉｇｍａＤｅｌｔａＭｏｄｕｌａｔｉｏｎ（ＳＤＭ）方法进行了分析和性能比较．仿真结果表明这两种方法在量化精度上大大优于传统的一阶ＳＤＭ的方法．最后，本文给出了一个最优化算法在ＳＤＨ（ＳｙｎｃｈｒｏｎｏｕｓＤｉｇｉｔａｌＨｉｅｒａｒｃｈｙ）漂移产生中的应用实例．

Abstract

A novel method based on phase quantization is proposed in this paper to do timing synthesis such as timing recovery and jitter synthesis.The optimal performance can be achieved by Viterbi algorithm.Some practical implements of reduced complexity

namely T Viterbi and two order Sigma Delta Modulations（SDM）

are also explored.The simulation results show that the quantization error is much less than conventional simple SDM.We also use this method in jitter generation

which show great advantages.
