Abstract
In order to improve the accuracy, robustness, and practicability of modulation recognition of underwater acoustic (UWA) communication signals, a method based on the time-frequency analysis (TFA) and deep-learning framework is proposed in this paper. After simulating the modulation signals through the UWA channel, the time domain signals are pre-processed by the linear TFA method: synchrosqueezing transform (SST) that are converted into the two-dimensional TFA input data sets. The encoder-decoder classification (EDC) network is designed to extract both global and detailed features and recognize the modulation types of UWA communication signals. The simulation results illustrate that the proposed method has a good performance for classifying binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), binary frequency shift keying (2FSK), quadrature frequency shift keying (4FSK), and linear frequency modulation (LFM) signals.
