| 摘 要： | 跳频信号的同步过程是跳频通信系统的关键.针对网形跳频网络中同步难的问题,提出了一种基于混沌序列的动态双频跳频同步方案.该方案采用混沌系统生成分布式跳频序列,同时引入并行解调器结构实现双频跳变的时序控制.仿真结果表明,方案可有效应对慢跳频通信系统中常见的部分频带干扰和强单频干扰,且同步建立过程简单迅速,系统的稳定性和安全...

| Abstract: | The synchronous process of frequency-hopping signals is the key technology in FH system.In order to reduce the difficult of synchronization in meshed FH network,a new issue which is based on double frequency hopping program and Chaotic Sequence has been promoted.In the modeling process,use a distributed hopping sequences which generated by chaotic system and a parallel demodulator structure to achieve the dual-frequency hopping timing control.The simulation results shows that the solution has a good perform... |
