    This paper summarizes the definition and validation of two complementary new strategies, to invert incomplete Global Navigation Satellite System Radio-Occultation (RO) ionospheric measurements, such as the ones to be ...
  • Matrix completion and extrapolation via kernel regression 

    Giménez Febrer, Pedro Juan; Pagès Zamora, Alba Maria; Giannakis, Georgios B. (2019-10-01)
    Article
    Open Access
    Matrix completion and extrapolation (MCEX) are dealt with here over reproducing kernel Hilbert spaces (RKHSs) in order to account for prior information present in the available data. Aiming at a fast and low-complexity ...
  • Spectral weighting orthogonal matching pursuit algorithm for enhanced out-of-band digital predistortion linearization 

    Gilabert Pinal, Pere Lluís; López Bueno, David; Montoro López, Gabriel (2018-01-01)
    Article
    Open Access
    This paper presents a new variant of the orthogonal matching pursuit (OMP) algorithm for reducing the computational complexity of the digital predistortion (DPD) behavioral model in the forward path. The proposed spectral ...
  • Differential 8-APSK monolithically integrated dual-EML transmitter for flexible coherent PONs 

    Velásquez Micolta, Juan Camilo; Tabares Giraldo, Jeison; Prat Gomà, Josep Joan (2019-06-01)
    Article

    We experimentally demonstrate a simultaneous amplitude and phase modulation of a monolithically integrated dual electro-absorption modulated laser. The proposed technique combines a 4-ary direct phase modulation with a ...
  • Conformal transformation of Dyakonov surface waves into bound states of cylindrical metamaterials 

    Kajorndejnukul, Veerachart; Artigas García, David; Torner Sabata, Lluís (American Physical Society (APS), 2019-11-05)
    Article
    Open Access
    We put forward the use of transformation optics to map surface waves that exist as one-dimensional modes supported by anisotropic structures into bound states in two-dimensional geometries. Specifically, we show the conformal ...

    Article
    Open Access
    The current constant growth in mobile networks' traffic demands caused by the popularization of cloud and streaming services on personal devices, requires architectural changes so as to fulfill all new 5G mobile network ...
  • Digital predistorters go multidimensional: DPD for concurrent multiband envelope tracking and outphasing power amplifiers 

    Gilabert Pinal, Pere Lluís; Montoro López, Gabriel; Vegas Garcia, Ángel; Ruiz Lavin, Maria de las Nieves; García García, José Ángel (2019-05-01)
    Article
    Open Access
    Over at least the last two decades, digital predistortion (DPD) has become the most common and widespread solution to cope with the power amplifier's (PA's) inherent linearity-versus-efficiency tradeoff. When compared with ...
