      Aquest treball consisteix en l’estudi, el disseny i la implementació d’un prototip d’amplifi- cador d’àudio commutat. En termes generals, els principals subsistemes d’un amplificador commutat són la font d’alimentació, ...

    • Dynamic selection and update of digital predistorter coefficients for power amplifier linearization 

      Pham, Thi Quynh Anh; López Bueno, David; Montoro López, Gabriel; Gilabert Pinal, Pere Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper, a new method for dynamically estimating and updating the coefficients of a digital predistortion (DPD) linearizer is presented. By means of the partial least squares (PLS) algorithm, the basis matrix used ...
