Communication signal modulation type intelligent identification method for industrial internet

The invention discloses a communication signal modulation type intelligent identification method for an industrial internet, relates to the field of radio, and is used for solving the problems of poor robustness, poor completeness and poor practicability in the prior art. The method comprises the following steps: carrying out preliminary classification on received signals by utilizing a signal identification network based on MobileNet; classification of amplitude modulation and frequency modulation is carried out by using a signal identification network based on KAN-LSTM; and according to classification results of the previous two steps, outputting a signal modulation type identification result, or continuing to use a KAN-LSTM-based signal identification network, a MobileNet-based signal identification network or a multi-modal feature fusion network to carry out step-by-step subdivision so as to obtain the signal modulation type identification result. The accuracy and robustness of the signal modulation type
