Abstract

La présente invention porte sur des procédés, sur des dispositifs et sur des systèmes pour des systèmes de communication sans fil à base de capteur qui utilisent un échantillonnage compressif. Selon un mode de réalisation, le procédé permettant l'échantillonnage de signaux consiste à : recevoir, sur un canal sans fil, une transmission d'équipement utilisateur basée sur une combinaison de type S-sparse d'un ensemble de vecteurs ; transposer par abaissement de fréquence et discrétiser la transmission reçue pour créer un signal discrétisé ; corréler le signal discrétisé avec un ensemble de formes d'onde de détection pour créer un ensemble d'échantillons, le nombre total d'échantillons dans l'ensemble étant égal au nombre total de formes d'onde de détection dans l'ensemble, l'ensemble de formes d'onde de détection ne correspondant pas à l'ensemble de vecteurs et le nombre total de formes d'onde de détection dans l'ensemble de formes d'onde de détection étant inférieur à un nombre total de vecteur dans l'ensemble de vecteurs ; et transmettre au moins un échantillon de l'ensemble d'échantillons à un processeur central distant.
