Semantic CSI Feedback for Beam Selection: When Task-Aware Embeddings from Sparse Pilots Outperform Full-Bandwidth Reconstruction

Cristian J. Vaca-Rubio, Konstantinos Vandikas, Aneta Vulgarakis Feljan

Classical CSI feedback in FDD massive MIMO transmits a compressed reconstruction of the channel, optimizing fidelity to the original signal regardless of the downstream task. We pr…

Context-Aware Markov VAE for CSI Compression in Wireless Systems

Efstathios Chatziloizos, Konstantinos Vandikas, Aneta Vulgarakis Feljan +2

This paper considers neural channel state information (CSI) compression for time-varying massive multiple-input multiple-output (MIMO) channels in frequency division duplex (FDD) s…
