  • A new digital predictive predistorter for behavioral power amplifier linearization 

    Montoro López, Gabriel; Gilabert Pinal, Pere Lluís; Bertran Albertí, Eduardo; Cesari Bohigas, Albert; Silveira, Daniel D. (Institute of Electrical and Electronics Engineers (IEEE), 2007-06)
    Article
    Open Access
    This letter presents a new digital adaptive predistorter (PD) for power amplifier (PA) linearization based on a nonlinear auto-regressive moving average (NARMA) structure. The distinctive characteristic of this PD is ...
  • Application of pptimal delays selection on parallel cascade Hammerstein models for the prediction of RF-power amplifier behavior 

    Silveira, Daniel D.; Arthaber, Holger; Gilabert Pinal, Pere Lluís; Magerl, Gottfried; Bertran Albertí, Eduardo (2006-12)
    Conference lecture
    Open Access
    In this work two different black-box modeling strategies are combined in order to achieve improved RF Power Amplifier (PA) models based on measured input/output signals. The model validation is here done within the low ...
  • Heuristic algorithms for power amplifier behavioral modeling 

    Gilabert Pinal, Pere Lluís; Silveira, Daniel D.; Montoro López, Gabriel; Gadringer, Michael E.; Bertran Albertí, Eduardo (Institute of Electrical and Electronics Engineers (IEEE), 2007-10)
    Article
    Open Access
    This letter presents the use of two heuristic search algorithms, named simulated annealing and genetic algorithms, for the extraction of power amplifier (PA) behavioral model parameters. Their application in this letter ...
