A New Improved Multi-Sequence Frequency-Hopping Communication Anti-Jamming System

In order to address the challenge posed by existing anti-jamming methods (including intelligent anti-jamming techniques) that struggle to counter high-speed reactive jamming in complex jamming environments, we have developed a novel approach that involves leveraging intelligent jamming in such environments rather than merely attempting to evade jamming. Unlike existing anti-jamming techniques that extract energy from jamming signals as a power source, our proposed method can use intelligent reactive jamming signals as a positive factor in frequency detection. To be precise, we have designed an intelligent multi-sequence frequency hopping communication framework (IMSFH), which includes two stages: communication and training. Firstly, during the synchronous sequence transmission, supervised learning is used in the training stage to obtain the rules of reactive jamming through neural networks. In the communication stage, IMSFH using narrowband reception utilizes reactive jamming rules to improve the frequency-detection capability during actual payload transmission. The simulation results show that this method not only improves communication performance with the increase in jamming signal power and stronger anti-jamming ability when combating high-speed reactive jamming, but also better utilizes reactive jamming to improve communication performance in complex jamming environments.
