Beam scheduling policy for communications and PNT services from LEO satellites
Alejandro Gonzalez-Garrido, Francesco Menzione, Ottavio M. Picchi +1
Future low Earth orbit (LEO) constellations are expected to provide positioning, navigation, and timing (PNT) as a native service alongside broadband, removing the GNSS dependency…
On-board AI-based Channel Estimation for LEO NTNs
Mahdi Abdollahpour, Bruno De Filippo, Carla Amatetti +1
Artificial Intelligence(AI) methods have shown strong channel estimation performance in terrestrial networks, but they typically rely on substantial computational resources. As 6G…
Fast 5G Signal Acquisition by Using Non-Uniform Sampling
Alejandro Gonzalez Garrido, Carla Amatetti
This paper proposes a framework for fast signal acquisition based on deterministic non-uniform sampling, with emphasis on multi-coset architectures and receivers driven by known sy…
DRIFT: Joint Channel Estimation and Prediction Towards Pilotless 6G Non-Terrestrial Networks
Bruno De Filippo, Carla Amatetti, Alessandro Vanelli-Coralli
Non-terrestrial networks (NTNs) are expected to play a pivotal role in sixth-generation (6G) systems by enabling ubiquitous connectivity and massive communication. In this context,…
Toward Multi-Satellite Cooperative Transmission: A Joint Framework for CSI Acquisition, Feedback, and Phase Synchronization
Yiming Zhu, Yafei Wang, Carla Amatetti +5
The stringent link budget, caused by long propagation distances and payload constraints, poses a fundamental bottleneck for single-satellite transmission. Although LEO mega-constel…
A Ray-Based Characterization of Satellite-to-Urban Propagation
Nicolò Cenni, Marina Barbiroli, Vittorio Degli-Esposti +3
The evolution toward 6G communication systems is expected to rely on integrated three-dimensional network architectures where terrestrial infrastructures coexist with non-terrestri…
An SCMA Receiver for 6G NTN based on Multi-Task Learning
Bruno De Filippo, Carla Amatetti, Riccardo Campana +2
