In order to achieve efficient and reliable data transmission in complex electromagnetic environment, achieve real-time anti-interference and improve spectrum utilization of communication system, did a research on non-continuous OFDM(NC-OFDM), transform domain communication system(TDCS), spread spectrum technology and neural network algorithm. Artificial intelligence algorithm is applied to switch communication waveforms to resist different types of interference for the first time. Based on this, an intelligent anti-interference system based on radial basis neural network algorithm is designed. The three anti-jamming modes are introduced and simulated respectively, and their anti-interference ability and the feasibility of improving the spectrum utilization by switching waveforms are verified. The whole intelligent anti-interference system is simulated and analyzed. It basically satisfies the waveform selection requirements in the case of dealing with sudden interference, and can be applied to more communication scenarios than the conventional communication system.
