      Enabling ultra fast systems has been widely investigated during recent decades. Although polarization has been deployed from the beginning in satellite communications, nowadays it is being exploited to increase the throughput ...
    • Channel dependent mutual information in index modulations 

      Henarejos Hernández, Pol; Pérez Neira, Ana Isabel; Tato, Anxo; Mosquera Nartallo, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report

      Mutual Information is the metric that is used to perform link adaptation, which allows to achieve rates near capacity. The computation of adaptive transmission modes is achieved by employing the mapping between the Signal ...
    • Cramer-Rao bounds for SNR estimation of oversampled linearly modulated signals 

      López Valcarce, Roberto; Villares Piera, Nemesio Javier; Riba Sagarra, Jaume; Gappmair, Wilfried; Mosquera Nartallo, Carlos (2015-04-01)
      Article
      Open Access
      Most signal-to-noise ratio (SNR) estimators use the receiver matched filter output sampled at the symbol rate, an approach which does not preserve all information in the analog waveform due to aliasing. Thus, it is relevant ...
    • Exploratory analysis of superposition coding and rate splitting for multibeam satellite systems 

      Caus, Marius; Pastore, Adriano; Navarro Rodero, Mònica; Ramirez, Tomás; Mosquera Nartallo, Carlos; Noels, Nele; Alagha, Nader; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report

      The adoption of aggressive frequency reuse schemes along with interference management techniques has become the leading paradigm in satellite communications to increase the spectral efficiency. In general terms, one cannot ...
    • Neural network aided computation of mutual information for adaptation of spatial modulation 

      Tato, Anxo; Mosquera Nartallo, Carlos; Henarejos, Pol; Pérez Neira, Ana Isabel (2020-05-01)
      Article
      Open Access
      Index Modulations, in the form of Spatial Modulation or Polarized Modulation, are gaining traction for both satellite and terrestrial next generation communication systems. Adaptive Spatial Modulation based links are needed ...
    • Practical implementation of link adaptation with dual polarized modulation 

      Tato, Anxo; Mosquera Nartallo, Carlos; Henarejos Hernández, Pol; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
