First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.
首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

The thesis is based on the architecture of All-Digital Frequency and Phase Synthesizer (All-Digital PLL) which is published by Hugh Mair and Liming Xiu. The architecture makes multiple signals of the same frequency and the same phase difference the output of a voltage-control-oscillator to be the internal input of the DCO (flying-adder architecture), and we utilize the control word to decide the desired synchronized output signal.
中文摘要本论文是以Hugh Mair及Liming Xiu所提出之全数位频率与相位合成器架构(All-Digital PLL)为基础来做改良设计，此架构是以多个压控振荡器输出的相同频率及相同相位差的讯号，做为DCO(flying-adder architecture)的内部输出讯号，再以控制位元决定出所欲同步讯号。
