摘要:

介绍了跳频通信原理,利用Simulink仿真工具,建立快速跳频通信系统仿真模型,在不同干扰模式下进行仿真,分析了抗干扰性能,并在不同信道下完成仿真,接近真实干扰环境。最终得出结论,快速跳频系统具有较强的抗干扰与多径衰落能力,且随着调频速率的增高,该能力也在增强。

Abstract:

The principle of hopping communication is introduced,a fast frequency hopping communication system simulation model is built using the simulink tools,and different interference modes are simulated and analyzed for their anti-jamming performance.Simulations in different channels are conducted to approximate the real interference environment.Simulation results show that the fast frequency hopping communications system has good anti-interference and multipath fading performance,which increase with the frequency modulation rate.

Key words: FFH;simulink simulation;anti interference
