摘要
跳频组网的核心技术之一是跳频同步问题。对现有的跳频同步方案做了一些改进,分析了时间信息TOD与同步头频率使用原理、同步头频率捕获过程、跳频同步与跟踪过程。时分多址接入(TDMA)的前提条件需要跳频同步的完成,结合时隙同步方法和跳频同步技术阐述了基于TDMA的Ad Hoc网络跳频组网的实现过程。
Synchronization is the key techniques for frequency hopping（FH） network construction. This paper puts forward an improved scheme of frequency hopping synchronization based on correlative researches. It mainly analyzes the principle by using a method combining synchronization-head with time of day（TOD） and studies the process of capturing synchronization and tracking. Time Division Multiple Access（TDMA） protocol uses the orthogonality of time to achieve channel sharing after synchronization ＇ s achievement of a FH communication system. Slot synchronization and FH synchronization technique are used in this paper to realize TDMA-based Ad Hoc network construction.
