    • Design an implementation of a Class D Amplifier 

      Santana Ruiz, Sergio (Universitat Politècnica de Catalunya, 2016-06-30)
      Bachelor thesis
      Restricted access - author's decision
      This Project born at early 2016 when I talked with Nestor Berbel to ask him to be my tutor in my bachelor thesis. My idea was to implement an audio amplifier because I would like to understand how it works on low level. ...

    • 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
      Conference lecture
      Restricted access - publisher's policy
      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 ...

    • Evaluation of digital linearization techniques for PAs under 5G waveform operation in spectrum sharing scenarios 

      Cañal Blanco, Mireia; Mars Perez, Aitor (Universitat Politècnica de Catalunya, 2016-09-15)
      Bachelor thesis
      Open Access
      This project has been oriented to improve the efficiency and the linearization of power amplifiers (PA) with the combination of crest factor reduction (CFR) techniques and digital predistortion techniques (DPD). These ...

    • Evaluation of operational amplifier immunity by means of Weibull distribution 

      Fernández García, Raúl; Gil Galí, Ignacio (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Open Access
      The immunity of operational amplifiers is a trend topic for electromagnetic compatibility EMC community. Radiofrequency interference is usually applied to the operation amplifier and the voltage offset is monitored ...

    • Model order reduction techniques for power amplifier digital predistortion linearization 

      Mozos Ruiz, José Miguel (Universitat Politècnica de Catalunya, 2016-07-25)
      Bachelor thesis
      Open Access
      To address the known trade-off between linearity and efficiency of the PA, several linearization techniques have been proposed in the literature. Among them, the most widespread technique is now digital predistortion (DPD) ...

      Restricted access - author's decision
      The objective of this work was to design and ultimately provide a two-way universal broadband connectivity service for a national Spanish public entity and all its regional branches where IP traffic could be routed end-to-end ...

    • X-band UAV-SAR optimization and validation 

      Royo, Miquel (Universitat Politècnica de Catalunya, 2018-07)
      Bachelor thesis
      Open Access
      This project consists on the improvement of an already validated System, as it is the work of a finished PhD Thesis. Due to the wide range of that thesis, many sub blocs need to be revaluated and optimized. That is the ...
