Exact Payload-Decoupling Conditions for Pilot-Only BEM Channel Estimation With Application to OTFS
Gianmarco Romano, Francesco A. N. Palmieri, Stefano Buzzi +2
In high-mobility doubly dispersive links, basis expansion models (BEMs) reduce channel dimensionality, yet unknown payload symbols generally contaminate conventional matched-pilot…
Unsupervised Learning for Scalable Downlink Power Control in Cell-Free Massive MIMO
Giovanni Di Gennaro, Amedeo Buonanno, Gianmarco Romano +3
In cell-free massive multiple-input multiple-output systems, downlink power control is essential to ensure uniformly high service quality across users. Existing solutions range fro…
Probing Information Distribution in Transformer Architectures through Entropy Analysis
Amedeo Buonanno, Alessandro Rivetti, Francesco A. N. Palmieri +2
This work explores entropy analysis as a tool for probing information distribution within Transformer-based architectures. By quantifying token-level uncertainty and examining entr…
A General Framework for Scalable UE-AP Association in User-Centric Cell-Free Massive MIMO based on Recurrent Neural Networks
Giovanni Di Gennaro, Amedeo Buonanno, Gianmarco Romano +2
This study addresses the challenge of access point (AP) and user equipment (UE) association in cell-free massive MIMO networks. It introduces a deep learning algorithm leveraging B…
A Deep Learning Approach for User-Centric Clustering in Cell-Free Massive MIMO Systems
Giovanni Di Gennaro, Amedeo Buonanno, Gianmarco Romano +2
Contrary to conventional massive MIMO cellular configurations plagued by inter-cell interference, cell-free massive MIMO systems distribute network resources across the coverage ar…
