Scalable Attention for 5G NR Channel Estimation

Mahdi Abdollahpour, Marco Bertuletti, Yichao Zhang, Luca Benini, Alessandro Vanelli-Coralli

Attention-based neural estimators achieve strong channel-estimation accuracy, but the computational cost of global attention over the time-frequency resource grid grows quadratically with the number of subcarriers, and these estimators are typically tied to a single resource allo…

On-board AI-based Channel Estimation for LEO NTNs

Mahdi Abdollahpour, Bruno De Filippo, Carla Amatetti, Alessandro Vanelli-Coralli

Artificial Intelligence(AI) methods have shown strong channel estimation performance in terrestrial networks, but they typically rely on substantial computational resources. As 6G moves toward a unified architecture that will include Non-Terrestrial Networks (NTN) from day 0, ava…
