摘要
为了提高水声通信的保密性能,提出了一种简洁的混沌跳频图案实现方法。研究了量化logistic混沌序列产生的跳频图案性能,给出了平衡性、相关性、跳频间隔的仿真结果,验证了近距离水声通信中采用混沌跳频技术的可行性。
In order to enhance security of underwater communication, a method to realize the pattern of frequency hopping is proposed. Performance of the hopping pattern generated by quantized logistic chaotic sequence is studied. Feasibility of chaotic hopping technique used in short-range acoustic underwater communication is verified by simulated results in balance property, correlation and hopping gap.
