Resumo: A family of techniques aiming to perform blind equalization for Quadrature Amplitude Modulation (QAM) signals is presented. The proposed algorithms are decision directed and based on modi ed Constant Modulus (CM) criteria. Two approaches are used to develop the algorithms: the Stochastic Gradient Descent approach and the Normalized Constant Modulus Algorithm (NCMA) approach. Computer simulations con rm the expected results and show that the proposed algorithms outperform the conventional CM based algorithms.

Les algorithmes propos es sont dirig es par la d ecision et bas es sur des fonctions de coût du type Module Constante modi ees. Deux approches sont consid er ees: l'approche du Gradient Stochastique et l'approche du Normalized Constant Modulus Algorithm (NCMA). Les simulations num eriques con rment les r esultats attendus et montrent que les techniques propos ees am eliorent les performances des algorithmes classiques bas es sur la fonction de coût CM.Colloque Gretsi2012-12-07T14:34:45Z2012-12-07T14:34:45Z2005info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjectapplication/pdfFERNANDES, C.
