Download or read book Modeling Estimation and Optimal Filtration in Signal Processing written by Mohamed Najim and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide graduate students and practitioners with traditional methods and more recent results for model-based approaches in signal processing. Firstly, discrete-time linear models such as AR, MA and ARMA models, their properties and their limitations are introduced. In addition, sinusoidal models are addressed. Secondly, estimation approaches based on least squares methods and instrumental variable techniques are presented. Finally, the book deals with optimal filters, i.e. Wiener and Kalman filtering, and adaptive filters such as the RLS, the LMS and their variants.

Available in PDF, EPUB and Kindle. Book excerpt: L'étude des propriétés caractéristiques de signaux et systèmes, et la connaissance des outils mathématiques et des méthodes de traitement et analyse, prennent de l'importance et ne cessent d'évoluer. La raison en est que l'état actuel de la technique, particulièrement de l'électronique et de l'informatique, rend possible la réalisation de systèmes de traitement très avancés, efficaces et de moins en moins coûteux en dépit de la complexité. Le traitement du signal concerne les diverses opérations effectuées sur une grandeur physique analogique ou numérique dans le but d’une analyse, d’une interprétation ou de l’extraction d’informations. La maîtrise et la mise en oeuvre des techniques de traitement du signal nécessitent la connaissance de certains outils théoriques. Traitement numérique du signal expose les concepts de base de l’étude théorique et précise les méthodes courantes de traitement. Ce premier volume traite également de l'identification et la synthèse de lois de commandes dans le but de la stabilisation et de la régulation.

Download or read book Spectral Analysis written by Francis Castanié and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with these parametric methods, first discussing those based on time series models, Capon’s method and its variants, and then estimators based on the notions of sub-spaces. However, the book also deals with the traditional “analog” methods, now called non-parametric methods, which are still the most widely used in practical spectral analysis.

Download or read book Two dimensional Signal Analysis written by René Garello and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title sets out to show that 2-D signal analysis has its own role to play alongside signal processing and image processing. Concentrating its coverage on those 2-D signals coming from physical sensors (such as radars and sonars), the discussion explores a 2-D spectral approach but develops the modeling of 2-D signals and proposes several data-oriented analysis techniques for dealing with them. Coverage is also given to potential future developments in this area.

Available in PDF, EPUB and Kindle. Book excerpt: CE RAPPORT CONCERNE L'APPLICATION DE MODELES NON LINEAIRES A DES PROBLEMES CLASSIQUES DE TRAITEMENT DU SIGNAL: IDENTIFICATION DE FILTRES ET MODELISATION DE PROCESSUS. POUR ETUDIER CES MODELES, NOUS INTRODUISONS D'ABORD LES OUTILS APPROPRIES, PRINCIPALEMENT LES STATISTIQUES D'ORDRE SUPERIEUR A DEUX ET LES ALGORITHMES D'IDENTIFICATION DE PARAMETRES. NOUS NOUS CONSACRONS ENSUITE A L'ETUDE DE DIFFERENTS FILTRES NON LINEAIRES: FILTRES DE HAMMERSTEIN, DE VOLTERRA, NARMAX, BILINEAIRES ET RESEAUX DE NEURONES. CES FILTRES SONT COMPARES DANS LE CAS DE LA SOUSTRACTION DE BRUIT. CETTE APPLICATION NECESSITE DES HYPOTHESES SPECIFIQUES QUI SONT DETAILLEES POUR CHAQUE MODELE. CES TRAVAUX SONT VALIDES SUR DES SIGNAUX SONAR REELS. ENFIN, NOUS NOUS INTERESSONS A LA MODELISATION DE PROCESSUS NON LINEAIRES. LE PRINCIPE EST DE CARACTERISER UNE SERIE TEMPORELLE COMME LE RESULTAT DU FILTRAGE NON LINEAIRE D'UN BRUIT BLANC FICTIF. NOUS NOUS SOMMES PLUS PARTICULIEREMENT INTERESSES AUX PROCESSUS BILINEAIRES

This book was released on 2021-08-31 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume will deal with a presentation of the main matrix and tensor decompositions and their properties of uniqueness, as well as very useful tensor networks for the analysis of massive data. Parametric estimation algorithms will be presented for the identification of the main tensor decompositions. After a brief historical review of the compressed sampling methods, an overview of the main methods of retrieving matrices and tensors with missing data will be performed under the low rank hypothesis. Illustrative examples will be provided.
