Multi-band frequency spectrum prediction method of power wireless network and terminal

The invention discloses a multi-band frequency spectrum prediction method and terminal for a power wireless network, and the method comprises the steps: carrying out the preprocessing of the collected power spectrum density data of each band of the power wireless network at different historical times, extracting the features of the power spectrum density data layer by layer through stacked encoders, and enabling the step-by-step understanding of the abstract features of the data; time sequence feature learning is carried out on a feature matrix output by an encoder by using a long-short-term memory network, and a long-term dependency relationship in data can be obtained, so that the generalization ability and the prediction effect of a prediction model are improved; by introducing an attention mechanism, the model can dynamically adjust the weight according to the importance of input data, more accurately capture key feature information and dynamically pay attention to the most relevant part in an input seque
