摘要: Cet article presente et propose des techniques de detection aveugle multiutilisateur pour les systemes d’acces multiple par repartition dans l’espace. Dans ce cas utilisateurs peuvent etre separes a partir leur position l’espace, l’aide d’une antenne en reseau adaptative. L’algorithme du module constant (CMA), employe l’adaptation coefficients ponderation, est combine avec un concept decorrelation explicite, le but recuperer tous utilisateurs. Pour ameliorer la vitesse convergence l’erreur residuelle regime permanent, deux nouvelles approches sont introduites. Une premiere contribution une version moindres carres technique CMA multiutilisateur. methode adaptative ensuite proposee explicite. Des resultats simulation illustrent gains performances.
