摘要
提出了一种为实现高速数据传输和强抗干扰性且具有多址组网能力的高速跳频通信系统的方案。采用同步字头和时间信息TOD相结合的方法实现跳频同步,采用时分多址(TDMA)方式进行跳频组网。首先研究了跳频同步方法及时间信息TOD的使用、跳频同步的捕获和跟踪、TDMA跳频组网、系统同步等关键核心问题,然后分析讨论了同步频率隐蔽性问题和最后对系统的同步性能进行了简要分析,取得了满意的结果。
To implement high-speed data-transmit, good anti-jamming and multi-address building-net, a scheme for a high-speed FH communication system is proposed in the paper. FH synchronization is set up using the method of combining synchronization head with time of day (TOD), FH building-net using TDMA. First the paper deals with a method of FH synchronization, time of day (TOD), capture and tracking of FH synchronization, FH building-net using TDMA,and system synchronization. Then concealment of synchronization frequency is analyzed and discussed. Finally performance of synchronization is briefly analyzed and a satisfactory result is achieved.
