Distributed Precoding Systems in Multi-Gateway Multibeam Satellites: Regularization and Coarse Beamforming
Carlos Mosquera, Roberto Lopez-Valcarce, Vahid Joroughi
This paper deals with the problem of beamforming design in a multibeam satellite, which is shared by different groups of terminals -clusters-, each served by an Earth station or ga…
Generalized Multicast Multibeam Precoding for Satellite Communications
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira
This paper deals with the problem of precoding in multibeam satellite systems. In contrast to general multiuser multiple-input-multiple-output (MIMO) cellular schemes, multibeam sa…
Precoding in Multigateway Multibeam Satellite Systems
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira
This paper considers a multigateway multibeam satellite system with multiple feeds per beam. In these systems, each gateway serves a set of beams (cluster) so that the overall data…
On-Board Beam Generation for Multibeam Satellite Systems
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira +1
This paper aims at designing an on-board beam generation process for multibeam satellite systems with the goal of reducing the traffic at the feeder link. Full frequency reuse amon…
