  • Caractérisation des signaux radio avec des outils de traitement d’images 

    Morral Adell, Gemma (Universitat Politècnica de Catalunya, 2011-05-09)
    Master thesis (pre-Bologna period)
    Open Access
    Català: Ens basem en una representació 2D en temps-freqüència dels senyals rebuts després d'una detecció no-coherent ("square law detector" és a dir, es prèn el módul al quadrat de les NFFT dels senyals rebuts dins una ...
  • Non-linear spectral estimation 

    Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 1987)
    Conference report
    Open Access
    This work describes the use of constraints in variational procedures for spectral analysis. It is reported how the designer in a variational approach for spectral estimation has to select a set of constraints. At the same ...
  • On the inverse windowed Fourier transform 

    Rebollo Neira, Laura; Fernández Rubio, Juan Antonio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-11-30)
    Article
    Open Access
    The inversion problem concerning the windowed Fourier transform is considered. It is shown that, out of the infinite solutions that the problem admits, the windowed Fourier transform is the "optimal" solution according to ...
