    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 ...
  • Image restoracion using the w-slice method 

    Sayrol Clols, Elisa; Chrysostomos, Nikias; Gasull Llampallas, Antoni (1995-08)
    Article
    Accés obert
    We propose the use of higher order statistics (HOS)-based methods to address the problem of image restoration. The restoration strategy is based on the fact that the phase information of the original image and its HOS are ...
  • Non-linear spectral estimation 

    Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 1987)
    Text en actes de congrés

    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
    Accés obert
    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 ...
