摘　　要：同步技术是跳频通信系统的关键技术之一。针对高速跳频通信系统中同步的要求,采用同步头与时间信息相结合的方法实现跳频同步。文章研究了同步序列格式、跳频图案同步、位同步等问题,分析了同步性能,使用Matlab6.5完成了仿真验证。同步性能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。Synchronization is one of the key techniques for frequency-hopping （FH） communication system.Based on the requests of synchronization for a high-speed FH communication system,we achieved synchronization by using a method combined synchronizationhead with time of day（TOD）. Mainly the paper studies the structure of synchronization sequence, synchronization of hopping pattern, bit synchronization,and so on.The performance of synchronization is analyzed and the simulation is completed by using Matlab 6.5.The performance of synchronization shows that the synchronization of FH communication system makes synchronization time short, capture probability high, false probability low.
