End-to-End Deep Learning for CSI Estimation and Feedback in Large-Scale RIS-Assisted Wireless Systems

Simulation results indicate that the proposed E2E-CsiNet outperforms representative CSI feedback methods and deep learning–based end-to-end estimation and feedback baselines and achieves superior accuracy in CSI reconstruction.

Deep Learning-Enabled Energy-Efficient Joint CSI Estimation and Phase Shift Prediction in Large-Scale RIS-Assisted NOMA Systems

In large-scale reconfigurable intelligent surface (RIS)-assisted non-orthogonal multiple access (NOMA) systems, achieving energy-efficient communication while obtaining full channel state information (CSI) is challenging due to prohibitive pilot overhead. The joint CSI estimation and RIS phase shift prediction pose a t...

URP-FL: Robust and Personalized Federated Learning under Heterogeneous and Adversarial Conditions

Federated learning is appealing for privacy-sensitive network systems, yet its practical deployment remains hindered by the following three recurring challenges: (1) client drift under non-IID data, (2) vulnerability to corrupted updates, and (3) the communication cost of repeated model exchange. Most existing approach...
