摘要
跳频通信系统的关键技术是跳频序列的同步。本文利用混沌信号Logistic序列作跳频码,取代跳频通信中的伪随机序列,并采用动态双频同步方案使同步头信号同步,解决了混沌跳频序列的同步难题,进而实现发射系统和接收系统的混沌同步。在Matlab7.0/Simulink动态仿真平台,搭建了一个基于该同步方案的跳频通信系统,仿真结果表明该同步方案用于跳频通信可获得满意的通信效果。
The key technique is synchronization of frequency-hopping（FH） sequence in frequency-hopping communication system.The author using Logistic chaotic sequence as FH codes to substitute the common pseudo-noise sequence in FH communication.And it adopts dynamic double frequency to realize the synchronization of synchronization-head signal,so it can achieve the synchronization of chaos between transmitting terminal and receiving end.In this paper,based on the Matlab7.0/Simulink platform,modeling and simulation are implemented,and analyze the results,which show that the synchronous method acquires the satisfying communication effect in FH communication.
