Presentation title: Underwater Acoustic Signal Modulation Recognition Technology based on Feature Fusion and Lightweight Neural Network
Abstract: In order to make full use of the channel resources of underwater acoustic communication, the transmitters often use adaptive modulation and coding technology, which require the receivers to use automatic modulation recognition technology. However, the complex and changeable underwater channel environment with serious noise interference brings great challenges to the receiver to identify the modulation mode correctly. In addition, the real-time communication and the diversity of modulation mode put forward higher requirements for the modulation mode recognition technology. In order to solve the above problems, combined with the classical theory of multi-source specific feature extraction of underwater acoustic signal and the automatic abstract feature extraction method of neural network, we propose the underwater acoustic signal modulation recognition technology based on feature fusion and lightweight Neural Network. We extract the multi-source specific features of underwater acoustic signals according to the inherent differences of different modulation modes, and use the automatic feature extraction ability of lightweight hybrid neural network to extract the abstract features of underwater acoustic signals. Based on the feature fusion theory, the two kinds of features are fused into a more complete and more effective feature set.
