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。

Then, we discuss a robust implementation of the pilot-symbol-aided estimator that is insensive to channel statistics. The analysis of these algorithms is made by computer simulation. Finally, combinating with the application of channel estimation , we present two techniques: STBC (space-time block coding) and STTC (space-time trellis coding) to improve the performance of channel parameter estimation.

在基于导频的估计中，研究了基于MMSE下二维导频辅助信道估计，并结合无线信道的统计特性在一般不可知的条件下，给出了一种对无线信道的统计特性不是很敏感的鲁棒的二维导频辅助信道估计器，通过实验仿真证明其有效性。
