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
Accés obertThis 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 ... -

Analysis of variations of volterra series models for RF power amplifiers
Silveira, Daniel D.; Gilabert Pinal, Pere Lluís; Dos Santos, Alexandre B.; Gadringer, Michael E. (2013)
Article
Accés restringit per política de l'editorialThis article discusses several different implementations of Volterra seriesmodels, and performs a fair comparison between them using measured data and well known figures of merit. Among the implemented models, an approach ... -
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)
Comunicació de congrés
Accés obertIn 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
Accés obertThis 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 ... -
