    • 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 ...

    • A recursive digital predistorter for linearizing RF power amplifiers with memory effects 

      Gilabert Pinal, Pere Lluís; Montoro López, Gabriel; Cesari Bohigas, Albert (2006-12)
      Conference lecture
      Open Access
      A nonlinear auto-regressive moving average (ARMA) structure capable of compensating nonlinear memory effects in RF power amplifiers is here presented. Results on the linearity improvement, in both in-band and out-of-band ...
