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...

Low-Rank Prior-Guided Rank-One Sensing for Efficient CSI Feedback

A low-rank prior-guided (LRP) framework that performs learnable rank-one sensing at the user equipment to compress CSI into low-dimensional codewords, and reconstructs CSI by direct rank-one synthesis at the base station is proposed.
