Abstract	Toute forme de signal mettant en oeuvre une sommation de porteuses (orthogonales ou non) genere de fait des fluctuations temporelles, qui selon l'occurrence et l'amplitude, peuvent occasionner des distortions severes au passage d'elements non lineaires. Ces fluctuations sont le plus souvent designees sous l'acronyme Peak to Average Power Ratio (PAPR). Ce PAPR peut etre tres eleve et il est alors necessaire de le diminuer en proposant des methodes appropriees. Ce document d'HDR synthetise l'ensemble de mes activites de recherche entre 1997 et 2010. Il aborde de facon tres large la problematique de reduction du PAPR dans des problematiques variees (OFDM, radio logicielle, radio intelligente) et des contextes differents (projets collaboratifs et bilateraux). J'ai ete amene dans ce cadre a encadrer des etudiants en these ainsi que des post-doctorants.
