跳频通信系统中同步技术研究

摘要

Synchronization is one of the key technologies of FH communication.The synchronization of frequency hopping is achieved by adopting synchronization head and time of day to meet the requirement of practical development of FH communication system.The method of frequency-hopping synchronization, the format of synchronization information and the capture of synchronization are studied, and the performance of synchronization is analyzed.The results show that the FH communication system has characteristics of short synchronization time, high capture probability and low false probability.%同步技术是跳频通信系统关键技术之一.针对跳频通信系统中同步的要求,采用同步字头与时间信息相结合的方法实现跳频同步.首先研究了跳频同步方法、同步信息格式和初始同步等问题,最后对同步性能进行了分析.结果表明,该跳频通信系统的同步时间短、捕获概率高、虚警概率低.
