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 concept of digital life was first presented in computer simulation experiment by Thomas.S.Ray. Based on it, the theory knowledges were introduced such as complex adaptive system and Agent model-building. Then two kinds of different digital lives and their coexistence environment were constructed. Nature lives' most foundational biological phenomenas like reproduction and annihilation were simulated. The interactive behavior between individual and community was observed by visualization windows. Finally, the inscrutability and emergence of the results were attained, and the simulation for two digital lives with Swarm was accomplished.
