Simulation of Nonlinear Multi-Frequency Interference Detection Method for Electronic Communication Mutation
The most important feature of electronic communication technology is the high risk of failure.In order to further optimize the anti-jamming performance of network communication,this article puts forward a method of de-tecting abrupt nonlinear multi-frequency interference in electronic communication.The Frequency Modulated Contin-uous Wavec(FMCW)principle was introduced to calculate the distance and speed between different signals and deter-mine the range of abrupt signal,thus screening out the abrupt nonlinear multi frequency interference during electronic communication.Then,Wigner-Ville distribution was used to transform the spectrograms of all multi-frequency inter-ference signals,thus obtaining the true labels of interference signals.Correspondingly,a spectrogram of abrupt nonlin-ear multi frequency interference signals was constructed.Meanwhile,spectral features were extracted by convolution neural networks,and then the feature vectors were input into the long-term and short-term memory network for detec-tion.Finally,the detection of abrupt nonlinear multi frequency interference in electronic communication was comple-ted.Experimental results show that the interference detection cost less than 20ms,and the method is not affected by the fluctuation of the communication content length threshold and the coverage threshold of the similar content.And the missed detection rate is always less than 1.0%.
