Abstract:

The technical difficulty of antifollower jamming in communication systems is a wide concern in the peer. In order to solve the problem of difficulty to achieve antifollower jamming, a new identification method of follower jamming is proposed in this paper based on the characteristics of it and then follower jamming is cancelled out. A hardware-in-the-loop simulation platform is built by using FPGA. Then, experimental verification for mitigating performance of follower jamming is conducted based on the platform and the proposed method. Results show that signal-interference ratio (SIR) promotion is different for different jamming frequencies and the jamming mitigation performance is affected by interference intensity. The average SIR promotion can reach 10 dB when variance of jamming signal is between 0.75 and 1.5. In other cases, average SIR promotion is less than 10 dB. The proposed suppression method provides a useful way to antifollower jamming in frequency hopping (FH) communication.
