Multi-Agent Reinforcement Learning for Joint Handover Management and Power Allocation in Multi-Orbit Satellite Networks
Yassine Afif, Ashutosh Balakrishnan, Philippe Martins +3
Future sixth-generation non-terrestrial networks are expected to combine low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary Earth orbit (GEO) satellites, whose comp…
Statistically Robust Resource Block Allocation for Satellite Communications
Chaitanya Manapragada, Laurent Decreusefond, Philippe Martins
It is critical to dimension (accurately estimate capacity of) a satellite system prior to deployment, as it is very expensive to reconfigure launched satellite systems that fail to…
Timing advance and Doppler shift estimation in LEO satellite networks: A recursive Bayesian study
Ashutosh Balakrishnan, Pierre Popineau, Philippe Martins
Low earth orbit (LEO) satellite based non-terrestrial networks are a key theme of the upcoming 6G networks. These space networks are proposed to be used for high-mobility use-cases…
Performance analysis of a RIS-assisted communications
Hamza Adrat, Laurent Decreusefond, Philippe Martins
Reconfigurable Intelligent Surfaces (RIS) are currently considered for adoption in future 6G stantards. ETSI and 3GPP have started feasibility and performance investigations of suc…
