跳频通信系统抗干扰性能分析

Anti-Jamming Performance Analysis of FH Communication System

在介绍跳频通信基本原理的基础上,分析了在部分频带干扰和宽带阻塞干扰这两种常见干扰下的跳频通信系统的抗干扰性能,并借助计算机仿真工具MATLAB进行程序仿真,得到了在两种干扰下的误码率—信噪比曲线,从而验证了由理论分析而来的结果。同时,提出了用信号分集来克服部分边带干扰,并分析了其效果。

Anti-jamming performance is analyzed under full-band noise jamming and partial-band noise jamming condition,which based on the FH communication principle.Using computer simulation tool MATLAB,BER-SNR curve figures are presented under above jamming conditions and theory analysis is validated.At the same time,the performance is analyzed by using signal diversity to overcome partial-band noise jamming.
