水声跳频通信系统抗干扰性能仿真研究

Simulation Research on Anti-jamming Performance in Underwater Acoustic Jump Frequency Communication System

跳频通信系统与常规定频通信系统相比具有较强的抗干扰能力。在介绍水声跳频通信基本原理的基础上,分析了在部分频带干扰下的跳频通信系统的抗干扰性能,并提出利用信号分集技术解决部分频带干扰问题。借助MATLAB仿真工具,得到不同情况下的误码率-信噪比曲线,从而验证了理论分析的结果。

Anti-jamming performance of jump frequency communication system is much better than regular communication system. The paper introduces underwater acoustic jump frequency communication principle. It analyzes anti-jamming performance under partial-band noise jamming condition and puts up singal diversity method to solve it. Using MATLAB simulation instrument, it presents BER-SNR. curve figures under different conditions and validates the theory analysis result.
