Research on Narrowband Interference Suppression Technology of UAV Network Based on Spread Spectrum Communication

With the rapid development of information technology and the increasing application of unmanned aerial vehicle (UAV) in various fields, UAV network is facing many challenges, such as complex electromagnetic environment, serious environmental interference and human interference. Therefore, higher requirements are put forward for its safety, reliability and adaptability in complex environment. In order to improve the anti-narrowband interference capability of UAV network, this paper proposes a narrowband interference suppression technology based on spread spectrum communication. The simulation results show that the method has a good effect on narrowband interference suppression, and provides an effective solution to the problem of narrowband interference suppression in UAV network.
