摘　　要：位同步是数字通信中必不可少的环节,位同步的功能的好坏直接关系到一个数字接收系统的性能。位同步有外同步与自同步之分,自同步主要有微分同步与积分同步2种。简要介绍了2种同步方法的工作原理及各自的优缺点,并主要介绍了这2种同步方式的鉴相器的区别。HDL是设计数字逻辑电路必不可少的通用工具,该文给出了位同步性能较好的积分型自同步的一个HDL实现。Bit synchronization is a necessary part of digital communication system. Its implementation influences the performance of a digital receiving system. There are two categories of bit synchronization： external synchronization and internal synchronization. Internal synchronization is mainly composed of differential bit synchronization and integral bit synchronization.The capabilities of the two categories of bit synchronization are analyzed. And difference between two phase discriminators are introduced in detail. HDL is an essential general tool in digital logical circuit design. A HDL implementation of the integral bit synchronization with good performance is provided.
