ANR SESAME: conSistent EStimation and lArge random MatricEs

Le projet SESAME financé par l'Agence Nationale de la Recherche dans le cadre du programme Masses de Données et COnnaissances (MDCO) est un projet sur 4 ans (2008-2011), prolongé 6 mois jusqu'en juin 2012. Les objectifs de ce projet sont de promouvoir et développer les techniques mathématiques issues de la théorie des matrices aléatoires pour l'étude des systèmes de communications mobiles. Une attention particulière sera portée aux problèmes d'estimation statistique où le nombre de paramètres à estimer est du même ordre que le nombre d'observations disponibles. Une telle configuration est fréquente en communications numériques.
