Cooperative diversity and orthogonal frequency division multiplexing (OFDM) are two key technologies for future wireless communication systems. One of the main problems of OFDM systems is the high peak-to-average power ratio (PAPR) of the transmitted signals, which may cause the introduction of intercarrier interference due to the presence of nonlinear(More)
– Le but de cet article est de proposer une famille de techniques d'´ egalisation aveugle de signaux du type QAM. Les algorithmes proposés sont dirigés par la décision et basés sur des fonctions de coût du type Module Constante modifiées. Deux approches sont considérées: l'approche du Gradient Stochastique et l'approche du Normalized Constant Modulus(More)
iii Acknowledgements My thesis has been developed under a double diploma (cotutelle) convention between the Université de Nice-Sophia Antipolis (UNSA), France, and the Universi-dade Federal do Ceará (UFC), Brazil. First, I would like to thank the CAPES agency of the Brazilian government for their financial support of my PhD by means of a scholarship. This(More)
