Accés restringit per política de l'editorialSignal processing in satellite applications is usually performed either on-ground or on-board, i.e. at the gateway station or in the payload. Within the framework of the European Space Agency (ESA) SatNEx III study, a ... -
Joint linear precoding and beamforming for the forward link of multi-beam broadband satellite systems
Devillers, Bertrand; Pérez Neira, Ana Isabel; Mosquera, C. (2011)
Text en actes de congrés
Accés restringit per política de l'editorialNext generation high throughput satellite systems are expected to rely on the deployment of a high number of beams in the user link, and therefore operate in an interference limited regime. This paper builds on the combination ... -
On-board beam generation for multibeam satellite systems
Joroughi, Vahid; Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Devillers, Bertrand (2017-03-27)
Article
Accés obertThis paper aims at designing an onboard beam generation process for a hybrid onboard on-ground multibeam satellite architecture. The proposed method offers a good tradeoff between total throughput and feeder link bandwidth ...
