Abstract

In order to solve the problem of the existing anti-jamming methods have difficulty against high-speed reactive jamming, this paper proposed a new method to leveraging jamming instead of avoiding jamming. To achieve this goal, it proposed an enhanced differential frequency hopping, which added the process of sending and processing training signals. In EDFH, it designed the frequency detection at receiving end to detect the combined signal(user signal plus jamming signal). It also designed a combined-signal matching filter at the receiver to improve the detection performance of the combined signal. Simulation results show that the proposed method performs well in combating high-speed reactive jamming, and the leveraging effect is also apparent as the communication performance increases as the speed and power of the jamming signal increase.
