摘要
给出了一种新的用于激光水下通信的时隙同步器；分析了该同步器的工作原理和性能指标；给出了测试结果，该时隙同步器结构简单、捕捉速度快、抗噪声性能好、可以满足信号检测与解调单元的要求。
In underwater laser communication with PPM, as the repetition frequency of the signalis low and the communication time is short, it is required that precise time slot synchronizingsignals be quickly built up. The slot synchronizer proposed in this paper can meet this re-quirement. It is a digital phase-locked loop consisting mainly of a type 8031 single-chip com-puter and a type 8254 programmable counter.The principle and performance of the synchro-nizer are discussed and test results are given.
