Dynamic selection and update of digital predistorter coefficients for power amplifier linearization
Conference lecture
Restricted access - publisher's policyIn 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
(Universitat Politècnica de Catalunya, 2016-09-15)
Bachelor thesis
Open AccessThis 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
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2016-07-25)
Bachelor thesis
Open AccessTo 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) ... -
Provisión de servicios de acceso de banda ancha a internet/intranet para ubicaciones de difícil cobertura
(Universitat Politècnica de Catalunya, 2016-05)

Restricted access - author's decisionThe 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
(Universitat Politècnica de Catalunya, 2018-07)
Bachelor thesis
Open AccessThis 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 ...
