摘　　要：同步是跳频通信系统关键技术之一。针对高速跳频通信系统中同步的主要要求,提出了一种高速跳频通信同步的方案,采用同步字头法和时间信息相结合的方法实现跳频同步。研究了系统定时,跳频图案同步,位同步等问题,并对其同步性能进行了分析。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 to frequency-hopping (FH) communication system. Based on the main requests of synchronization for a high-speed FH communication system, this paper puts forward a synchronization scheme of a high-speed FH system, which is achieved by using a method combined synchronization-head with time of day (TOD). This paper mainly studies time of system, synchronization of FH pattern, bit synchronization, and so on. The performance of synchronization shows that the synchronization of FH communication system makes synchronization time short, capture probability high, false probability low.
