Based on the successful application of generative adversarial network (GAN) models in field image generation, this article introduces GANs into deep learning for communication systems and surveys its modulation classification. To solve difficulties feature extraction, to address low recognition accuracy existing radio signal modulation-type methods, adapt complex electromagnetic environments with high noise interference intensity, presents a model high-order digital signals. This uses Morlet...
Few-Shot learning (FSL) is a new deep method, which has been successfully applied in many fields, but not well explored the field of communication. To adapt to application scenario signal modulation recognition when only small number samples types signals can be collected, novel FSL algorithm based on multi-channel feature fusion network named FFFNet proposed this paper. Specifically, time sequence firstly are preprocessed into time-frequency and constellation diagrams enhanced by reciprocal...
Few-Shot Learning (FSL) studies how to learn from a few samples, and it has been well applied in image classification. In order adapt the scenario where only small number of signal samples can be obtained complex electromagnetic environments, this paper designs few-shot recognition algorithm based on enhanced constellation diagrams for Multiple Phase Shift Keying (MPSK), Quadrature Amplitude Modulation (MQAM), (MAPSK) signals. The I/Q sequence is firstly converted into diagram, which...
