WaveCSI-Net: Adaptive Multi-Resolution Wavelet Network for Massive MIMO CSI Feedback

Massive MIMO relies on accurate CSI feedback, yet existing deep learning methods often neglect frequency characteristics or rely on computationally expensive global attention. Observations across extensive experimental datasets indicate that CSI energy tends to concentrate in dense low-frequency sub-bands, while sparse...

Dual-Domain Illumination Prior for Low-Light Remote Sensing Image Enhancement

A trainable dual-domain illumination-prior module that is jointly optimized with each host backbone and exploits frequency-domain and spatial-domain illumination statistics, which improves PSNR and SSIM over their corresponding baselines.
