To enhance automatic modulation recognition of radio frequency proximity sensors under low signal-to-noise ratio conditions.
Implemented a TFI enhancement network based on a per-pixel kernel prediction network
Utilized a convolutional neural network for classification
Denoised time-frequency images to improve input features for the classifier
Achieved over 97% average recognition accuracy at SNR above -10 dB
Significantly improved recognition accuracy under low SNR conditions
Demonstrated comparable denoising performance to traditional methods with reduced computational overhead
