摘要
同步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主要要求,提出一种基于时间信息TOD的跳频同步方案,并设计该同步方案的系统原理框图;研究同步序列格式和跳频同步的捕获和跟踪;分析该方案的同步性能。仿真结果表明,该跳频同步方案具有同步时间短,捕获概率高,虚警概率低和抗干扰能力强的特点。
Synchronization is one of the key techniques for Frequency Hopping （FH）communication system. Based on the main requirement of synchronization for FH communication system, a synchronization scheme based on the Time of Day（TOD） of FH system is presented in this paper. Configuration of the system model is given at first. Then the method of frequency hopping synchronization, the format of synchronization information and the capture of synchronization are studied in the paper. At last, the performance of synchronization is analyzed. The simulation results show that this method has the feature of short synchronization time,high capture probability,low false probability and high anti- jamming performance.
