An opportunistic cognitive radio communication through the exploitation of the small-scale fading mechanisms of the LTE mobile channel
(2013)
Article
Open AccessIn recent years, the cognitive radio technology has attracted the attention of all the players in the telecommunication field (i.e., researchers, industry, service providers, and regulatory agencies) as a way of facing the ... -
Hf modem with multilevel parallel transmission using coding and rice
(1989-12)
Article
Restricted access - publisher's policyWe present a parallel modem for 2400 b.p.s. data transmission over high-frequency (h.f.) ionospheric channels. Time-redundancy (convolutional coding) and frequency diversity (parallel transmission with pre-encoding) are ... -

La televisió digital terrestre: un color millor... i alguns grisos
(2014-12)
Article
Restricted access - publisher's policyEl 3 d’abril de 2010 es va produir la fi de les emissions de televisió analògica a l’Estat espanyol. És el que es coneix com l’apagada analògica. De llavors ençà s’inicià una nova etapa en la radiodifusió de la televisió ... -
Analysis of variations of volterra series models for RF power amplifiers
(2013)
Article
Restricted access - publisher's policyThis 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 ... -
Computationally efficient real-time digital predistortion architectures for envelope tracking power amplifiers
(2013-03-05)
Article
Open AccessThis paper presents and discusses two possible real-time digital predistortion (DPD) architectures suitable for envelope tracking (ET) power amplifiers (PAs) oriented at a final computationally efficient implementation ... -

Slew-rate and efficiency trade-off in slow envelope tracking power amplifiers
(2012-12-12)
Article
Restricted access - publisher's policyThis paper presents a study on the trade-off between the envelope’s slew-rate and the drain efficiency when slower envelopes are considered to dynamically supply the power amplifier (PA). This paper discusses a method ... -
On the reusage of primary radio resources through the exploitation of the spatiotemporal robustness of the MIMO transmissions
(2012-09-20)
Article
Open AccessThe spatiotemporal robustness of the MIMO transmissions is exploited aiming at inducing opportunistic secondary communications on the primary radio resources. The proposed model makes use of the smallest singular values ... -
Look-up table implementation of a slow envelope dependent digital predistorter for envelope tracking power amplifiers
(2012-02-13)
Article
Restricted access - publisher's policyThis letter presents a dynamic slow envelope dependent digital predistorter (SED-DPD) capable of compensating for the nonlinear distortion and memory effects that arise in envelope tracking (ET) power amplifiers (PAs) when ...
