DS/FH通信系统的跳频同步技术研究

Study on Frequency Hopping Synchronization Techniques of DS/FH Hybrid System

同步是DS/FH混合通信系统的关键技术之一。根据跳频系统中对同步的要求,介绍了一种适用于DS/FH混合扩频通信系统的跳频同步方法,采用同步字头和精准时间相结合的方法实现跳频同步。对同步性能进行了分析,结果表明该跳频同步方法同步时间短,捕获概率高。

Synchronization is the key technique of DS/FH hybrid communication system. In this paper we propose a scheme of design of frequency hopping synchronization systems. In this scheme, the frequency synchronization is implemented by using the methods of synchronization head message and TOD. The analytical results are given to show that the proposed scheme has better performance of synchronization time and probability of acquisition than other conventional scheme.
