Anti-jamming method for vehicle communication network based on internet of vehicles technology

In order to solve the problems of poor signal anti-interference ability, high error rate and low network coverage in traditional vehicle communication network and improve the communication quality of vehicle communication network, an anti-interference method of vehicle communication network based on Internet of Vehicle (IoV) technology is proposed. The maximum cellular rate resource reuse algorithm (MCRRA) is used to optimise the link resources of vehicle communication network, so as to realise the optimal allocation of vehicle communication network resources. Then, the wavelet denoising method is used to filter the signal noise after resource allocation in vehicle communication network. Finally, the improved threshold function method of wavelet transform is used to compensate the pseudo-Gibbs phenomenon and signal loss in vehicle communication network. Experiments show that this method can effectively suppress the interference of vehicle communication network. The error rate of the vehicle communication network using this method is only 10%, and the coverage rate is as high as 98.7%.
