      Satellite Precoding is a promising technique to meet the target data rates of the future high throughput satellite systems and the costs per bit as required by 5G applications and networks, but it requires strict synchronization ...

    • Multi-user precoder designs for RGB visible light communication systems 

      Viñals Terrés, Roser; Muñoz Medina, Olga; Agustín de Dios, Adrián; Vidal Manzano, José (2020-11-29)
      Article
      Accés obert
      In this paper, we design linear precoders for the downlink of a visible light communication (VLC) system that simultaneously serves multiple users. Instead of using phosphor-coated white light-emitting diodes (PWLEDs), we ...

    • On-board beam generation for multibeam satellite systems 

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

    • Robust power allocation algorithms for MIMO OFDM systems with imperfect CSI 

      Rey Micolau, Francesc; Lamarca Orozco, M. Meritxell; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-03-31)
      Article
      Accés obert
      This paper presents a Bayesian approach to the design of transmit prefiltering matrices in closed-loop schemes robust to channel estimation errors. The algorithms are derived for a multiple-input multiple-output (MIMO) ...
