摘　　要：同步是通信系统中一个非常重要的实际问题。同步系统性能的降低会导致通信系统性能的降低,甚至使通信系统不能正常工作。因此,同步是信息能够正确可靠传输的前提。介绍一种基于单片机的锁相环位同步提取技术的原理及算法。Synchronization is a very important practical problem in the communication system. In the communication system, reducing synchronous system function would cause communication system function to lower, even ＂making the communication system can＇t work normally. Therefore, synchronous is the precondition that the information can be transferred corrected. This paper discusses an extraction technology of bit synchronization signal based on singlechip.
