A new non-linear system for estimating and suppressing narrowband interference in PN spread spectrum modulation
(1998)
Conference report
Open AccessThis work develops a novel dynamic fuzzy logic system that, based on a fuzzy basis function expansion, successfully solves the non-linear problem of narrowband interference prediction and rejection in DS-SS. A fuzzy basis ... -
A novel methodology for adaptive community detection
(Universitat Politècnica de Catalunya, 2019-06)
Bachelor thesis
Open AccessCommunity detection and statistical dependence detection between different sets of data are two very intertwined topics of research with many real world applications in areas involving information science resources, such ... -
A statistical reference criterion for adaptive filtering
(Institute of Electrical and Electronics Engineers (IEEE), 1996)
Conference report
Open AccessA cost function for adaptive filtering is proposed, based on the statistical reference criterion. The purpose of this criterion is to enforce a given probability density function at the output of a system. The only ... -

Adaptive blind equalization using weighted cumulant slices
(Institute of Electrical and Electronics Engineers (IEEE), 1994)
Conference report
Open AccessMany linear methods have been proposed in the literature to blindly estimate the ARMA parameters of a time series using HOS. Nevertheless, they are mainly off-line and not much has been done in the adaptive case. The method ... -

An adaptative fuzzy logic enhancer for rejection of narrowband interference in DS-Spread Spectrum
(1998)
Conference report
Open AccessThis work develops a novel adaptive fuzzy line enhancer that, based on a fuzzy basis function expansion, successfully solves the non-linear problem of narrowband interference estimation and rejection in direct sequence-spread ... -
An adaptive multiresolution method for speckle noise reduction in synthetic aperture radar images
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Conference report
Open AccessThis paper introduces a method for speckle noise reduction based on multiresolution algorithms and a new adaptive approach. It combines the characteristics for additive noise reduction of soft thresholding with the ... -
Application of hyperstability theory to interference cancelling
(O.YUKSEL IEEE, 1994)
Conference report
Open AccessAn alternative to the usual adaptive noise cancelling method devoted to removing interference is presented. In the conventional methodology to implement adaptive cancellers a reference signal is necessary correlated with ... -
Approximation of face images by analytical model
(Universitat Politècnica de Catalunya / École polytechnique fédérale de Lausanne, 2012-02)
Master thesis (pre-Bologna period)
Open Access
Covenantee: École polytechnique fédérale de LausanneEnglish: in this thesis, we address the problem of learning a face manifold model from an input data, consisting of 2D face images such that the input images can be approximated well using the learned manifold. We compute ... -
Blind wideband source separation
(1994)
Conference report
Open AccessThis paper deals with the general problem of separating two independent wideband sources when they are mixed by unknown filters. In order to solve this problem, a backward framework is proposed which is composed of two ... -
