    • Psi_B-energy operator and cross-power spectral density 
      Article dans une revue avec comité de lecture
      CHONAVEL, Thierry; CEXUS, Jean-Christophe; ccBOUDRAA, Abdel-Ouahab (Elsevier, 2014)
      In this paper we consider the hermitian extension of the cross-Psi_B-energy operator that we will denote by Psi_H. In addition, cross energy terms are formalized through multivariate signals representation. We investigate ...
    • On signals compression by EMD 
      Article dans une revue avec comité de lecture
      KHALDI, Kais; ccBOUDRAA, Abdel-Ouahab (IET, 2012)
      In this letter a new signals coding framework based on the Empirical Mode Decomposition (EMD) is introduced. The EMD breaks down any signal into a reduced number of oscillating components called Intrinsic Modes Decomposition ...
    • Analysis of multicomponent LFM signals by Teager-Huang-Hough Transform 
      Article dans une revue avec comité de lecture
      BOUCHIKHI, Abdelkhalek; CEXUS, Jean-Christophe; CHONAVEL, Thierry; ccBOUDRAA, Abdel-Ouahab (Institute of Electrical and Electronics Engineers, 2014)
      A novel detection approach of linear FM (LFM) signals, with single or multiple components, in the time-frequency plane of Teager-Huang (TH) transform is presented. The detection scheme that combines TH transform and Hough ...
    • A New class of multi-dimensional Teager Kaiser and higher order operators based on directional derivatives 
      Article dans une revue avec comité de lecture
      SALZENSTEIN, Fabien; CHONAVEL, Thierry; ccBOUDRAA, Abdel-Ouahab (Springer Verlag, 2013)
      This work aims at introducing some energy operators linked to Teager-Kaiser energy operator and its associated higher order versions and expand them to multidimensional signals. These operators are very useful for analyzing ...
    • EMD-Based Filtering Using Similarity Measure Between Probability Density Functions of IMFs 
      Article dans une revue avec comité de lecture
      KOMATY, Ali; AUGIER, Benoit; DARE-EMZIVAT, Delphine; ccBOUDRAA, Abdel-Ouahab (Institute of Electrical and Electronics Engineers, 2014)
      This paper introduces a new signal-filtering which combines the empirical mode decomposition (EMD) and a similarity measure. A noisy signal is adaptively broken down into oscillatory components called intrinsic mode functions ...
    • Analysis of intrinsic mode functions: A PDE approach 
      Article dans une revue avec comité de lecture
      DIOP, El Hadji; ccALEXANDRE, Radjesvarane; ccBOUDRAA, Abdel-Ouahab (Institute of Electrical and Electronics Engineers, 2010)
      The empirical mode decomposition is a powerful tool for signal processing. Because of its original algorithmic, recent works have contributed to its theoretical framework. Following these works, some mathematical contributions ...
    • A review of energy storage technologie sfor marine current energy systems 
      Article dans une revue avec comité de lecture
      ZHOU, Zhibin; CHARPENTIER, Jean-Frederic; TANG, Tianhao; ccSCUILLER, Franck; BENBOUZID, Mohamed (Elsevier, 2013)
      Increasing concerns about the depletion of fossil resources and the issue of environment lead to a global need for producing more clean energy from renewable sources. Ocean is appreciated as a vast source of renewable ...
