This invention proposes a gated time-series graph fusion-based learning signal modulation recognition method, relating to the fields of pattern recognition and intelligent information processing. The method uses the input IQ signal as the basic input, introduces an amplitude-phase adaptive filter, and adaptively emphasizes frequency band features relevant to discrimination under the supervision of the modulation recognition task through parameterized modeling of the spectral amplitude and phase. In the discrimination stage, a classification framework combining temporal and structural modeling is adopted to mine complementary discrimination information of the modulation signal in both the temporal and structural dimensions. A long short-term memory network is used to perform temporal modeling of the signal frame sequence, capturing the dynamic evolution characteristics of the modulation signal. Based on the fusion features, a dynamic graph adjacency matrix that simultaneously reflects local time-delay correlation and global similarity is constructed, and inter-frame correlation information is propagated through a graph neural network. Finally, a hierarchical discrimination fusion module adaptively integrates embedding vectors from different layers of the temporal and graph branches.
