Model-Driven Deep Learning with Rank-One Sensing for Efficient CSI Feedback

Downlink channel state information (CSI) feedback is essential for beamforming optimization in frequency-division duplex (FDD) massive multiple-input multiple-output (MIMO) systems. However, the feedback overhead increases with the number of antennas and subcarriers, posing a major challenge to practical deployment. Al...

SpaceDiffusion: Over-the-Orbit Diffusion for Space Generate-and-Forward Communications

This paper analytically characterize the progressive token-reconstruction error and derive a diffusion-step activation threshold that predicts when SpaceDiffusion is expected to outperform conventional decode-and-forward (DF) relaying, and develops an energy-aware early-exit policy to efficiently deploy SpaceDiffusion...
