同步是数字通信中的一个关键功能，它的失败可能会对传输系统的性能产生灾难性的影响。此外，同步电路包含接收器硬件的如此大的部分，使得它们的实现对总成本具有实质性影响。由于这些原因，设计工程师特别关注新的和更有效的同步结构的开发。不幸的是，数字超大规模集成电路技术的出现已经从根本上影响了现代设计规则，到目前为止，大多数模拟技术已经完全过时。虽然数字同步方法现在在文献中已经很好地建立起来，但它们只以技术论文的形式出现，通常集中在特定的性能或实现问题上。因此，它们对于给一个在其他方面看起来不均匀的领域提供一个统一的观点几乎没有用处。人们普遍认为，只有为设计者提供一个坚实的理论框架，才能对数字同步有一个基本的理解，否则当他试图将其应用于新的情况时，他将不知道在哪里调整他的方法。本书的任务就是建立这样一个框架。
Synchronization is a critical function in digital communications; its failures may have catastrophic effects on the transmission system performance. Furthermore, synchronization circuits comprehend such a large part of the receiver hardware that their implementation has a substantial impact on the overall costs. For these reasons design engineers are particularly concerned with the development of new and more efficient synchronization structures. Unfortunately, the advent of digital VLSI technology has radically affected modem design rules, to a point that most analog techniques employed so far have become totally obsolete. Although digital synchronization methods are well established by now in the literature, they only appear in the form of technical papers, often concentrating on specific performance or implementation issues. As a consequence they are hardly useful to give a unified view of an otherwise seemingly heterogeneous field. It is widely recognized that a fundamental understanding of digital synchronization can only be reached by providing the designer with a solid theoretical framework, or else he will not know where to adjust his methods when he attempts to apply them to new situations. The task of the present book is just to develop such a framework.
