基于 Simulink 的高速跳频通信系统仿真

摘要

Frequency -hopping technology has characteristics of anti -disturbance,anti -noise, anti -attenuation and lower bit error rate.The simulation model of frequency hopping communication system is built by means of Simulink,provided by Matlab,based on the basic principle and realization methods of frequency hopping communication.In addition,each simulation model is introduced in detail, and the parameters can be set by GUI platform parameters setting.Meanwhile,the platform can show the indexes such as transmitter and receiver frequency hopped intuitively and the bit error rate,etc.The result indicates the system can normally work and achieve the expected effect.%跳频技术具有较强的抗干扰、抗噪声，抗频率选择性衰减的能力和较低的误码率。在阐述跳频通信基本原理和实现方法的基础上，利用 Matlab 提供的可视化工具 Simulink 建立了跳频通信系统仿真模型，详细阐述了各模块设计。仿真平台可以通过提供的可视化界面设置参数，同时可以直观地显示收发双发频率的跳变、误码率等重要指标。仿真结果表明，该跳频通信系统工作正常，达到了预期效果。
