The rapid expansion of pumped storage power stations in China highlights a critical engineering challenge: ensuring the stability of large-span underground caverns excavated in intensely fractured, mosaic-fragmented rock masses under low in-situ stress. Taking the Liyang Pumped Storage Power Station as a case study, th...
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...
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.
