This application relates to a communication signal receiving method, apparatus, device, and medium based on an attention mechanism. The method includes: constructing and training a multi-source coupled signal separation network consisting of an end-to-end encoder-separation module-decoder. In the network, the encoder first maps short-time overlapping segments in a mixed signal into high-dimensional feature representations, which are then concatenated along the time axis to form a mixed signal feature vector. Next, based on the attention mechanism process modeled by the separation module, a mask of the target signal is extracted from the mixed signal feature vector, and the target signal feature representation is separated using the mask. Finally, the decoder receives the target signal feature representation, reconstructs it segment by segment, and outputs the complete target signal by overlapping and superimposing the reconstructed signal segments. This application enables efficient and accurate reconstruction of target signals in complex electromagnetic environments, achieving accurate reception of communication signals and enhancing the robustness of the communication system.
