摘要
同步是跳频通信系统的关键技术之一.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,并采用滑动相关法使同步头信号同步,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,最后利用M atlab的S imu link进行仿真.结果表明:该同步方法用于跳频通信可获得满意的通信效果.
Synchronization is one of the key techniques to frequency - hopping （FH） communication system. This paper proposes to use the Logistic chaotic sequence as FH codes, replacing pseudo - noise sequence in FH communication. In order to solve the difficulty in synchronization of chaotic FH sequence, it adopts the sliding correlating mode to realize the synchronization of synchronization - head signal, so it can achieve the synchronization of chaos between transmitting terminal and receiving end. The MATLAB simulation is completed, which shows that the synchronous method acquires the satisfying communication effect in FH communication.
