| description | The invention discloses an underwater acoustic communication signal modulation mode identification method based on an improved gating network and a residual network. The identification method comprises the following steps: receiving an underwater acoustic signal; improving the gated recurrent neural network to extract time features of the underwater acoustic signals; improving the residual neural network, and introducing a self-attention mechanism to carry out weighted reprocessing to obtain underwater acoustic signal spatial features; based on the correlation between the time features and the spatial features of the underwater acoustic signals, using an adaptive fusion strategy to fuse the obtained time features and the obtained spatial features of the underwater acoustic signals; sending the fused features to a full-connection neural network for network training; and after feature extraction and fusion are carried out on a to-be-recognized underwater acoustic signal, inputting the to-be-recognized underwate |
