Communication interference signal type intelligent identification method

Abstract

The communication interference signal type intelligent identification method disclosed by the invention is high in identification rate, and solves the problem of interference signal identification in a complex spectrum environment. According to the technical scheme, the interference identification process is divided into a preprocessing part and a network identification part, time domain windowing, power normalization processing and Fourier transform are carried out on signals received by a receiver in the preprocessing part, and time domain data and frequency domain data are obtained; in the recognition network part, time domain data are input into a time domain feature extraction branch, and time domain features are obtained through a time domain convolution module and a time domain LSTM module; the frequency domain data is input into a frequency domain feature extraction branch, and frequency domain features is obtained through a frequency domain convolution module and a frequency domain LSTM module; the time domain features and the frequency domain features are sent to a fusion module for feature fusion; and finally, the obtained fusion features are sent to a classification module to carry out classification identification on the interference signals to obtain a type identification result of the interference signals.
