Abstract

La présente invention concerne un procédé d'émission de données dans un système de communication à multiplexage GFDM (multiplexage par répartition en fréquence généralisé) ayant N sous-porteuses avec M symboles dans chaque bloc de multiplexage GFDM. Le procédé d'émission comprend les étapes suivantes : sous-échantillonnage du vecteur de signal à émettre de taille MN par un facteur M; exécution d'un nombre M d'opérations de transformée de Fourier discrète, DFT, de taille N sur les échantillons de données sous-échantillonnés afin de délivrer des données de sortie de transformée DFT; et exécution d'un nombre N de M opérations de convolution circulaire de point sur les données de sortie des transformées DFT avec un filtre de mise en forme d'impulsions afin de délivrer le signal de sortie à multiplexage GFDM à émettre. La présente invention concerne également un mode de réalisation d'un récepteur permettant de mettre en œuvre une structure unifiée pour un récepteur ZF, MF et MMSE.
