  • Generalized multicast multibeam precoding for satellite communications 

    Joroughi, Vahid; Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel (2017-02-01)
    Article
    Open Access
    This paper deals with the problem of precoding in multibeam satellite systems. In contrast to general multiuser multiple-input-multiple-output cellular schemes, multibeam satellite architectures suffer from different ...
  • Multiple gateway precoding with per feed power constraints for multibeam satellite systems 

    Joroughi, Vahid; Vazquez, Miguel Angel; Pérez Neira, Ana Isabel (VDE Conference Publications, 2010)
    Conference report
    Restricted access - publisher's policy
    Multibeam satellite systems have been recently studied in order to provide broadband services to their coverage area by employing fractional frequency reuse pattern. Towards a more spectrally efficient system, the designer ...
  • Next generation multibeam satellite systems 

    Joroughi, Vahid (Universitat Politècnica de Catalunya, 2015-12-02)
    Doctoral thesis
    Open Access
    Satellite communication will play a central role towards fulfilling next generation 5G communication requirements. As a matter of fact, anytime-anywhere connectivity cannot be conceived without the presence of the satellite ...
  • On-board beam generation for multibeam satellite systems 

    Joroughi, Vahid; Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Devillers, Bertrand (2017-03-27)
    Article
    Open Access
    This 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 ...

  • Precoding in multigateway multibeam satellite systems 

    Joroughi, Vahid; Vazquez, Miguel Angel; Pérez Neira, Ana Isabel (2016-07)
    Article
    Open Access
    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 traffic is generated at different ...
