摘　　要：差分跳频信号的无线传输方式使得在接收时会包含干扰信号,影响差分跳频信号的正确接收。在研究差分跳频信号产生机理和信号特性基础上,根据差分跳频信号的统计独立性,提出一种基于JADE的差分跳频信号分离方法,并对所提出的方法进行了仿真。仿真结果表明,提出的方法可实现对混合信号中差分跳频信号的有效分离.The wireless transmission of differential frequency hopping signal can＇t avoid jamming signal in the received signal,and it will affect the correct receiving of the DFH signal.Based on studying the mechanism and characteristics of DFH signal,and utilizing the statistical independence of DFH signal,a method is proposed for separating DFH signal in mixed signals by JADE.The proposed method is simulated.The simulation result shows that the proposed method can effectively separate the DFH signal in the mixed signals.
