Abstract

L'invention concerne un système de communication comprenant un réseau de distribution hybride fibres optiques/câbles coaxiaux. Une extrémité de tête assure la transmission vers l'aval d'informations téléphoniques et de données de commande dans une première bande de fréquences, par un réseau de distribution hybride fibres optiques/câbles coaxiaux et la réception vers l'amont d'informations téléphoniques et de données de commande dans une seconde bande de fréquences par le réseau de distribution hybride fibres optiques/câble coaxial. L'extrémité de tête comprend un modem de tête pour porteuses multiples, pour moduler les informations téléphoniques destinées à l'aval sur une pluralité de porteuses orthogonales dans la première bande de fréquences et pour démoduler les informations téléphoniques, destinées à l'amont, modulées sur une pluralité de porteuses orthogonales dans la seconde bande de fréquences. Le système comprend des unités de service, activement connectées au réseau de distribution hybride fibres optiques/câbles coaxiaux, pour transmettre vers l'amont des informations téléphoniques et des données de commande et pour recevoir de l'aval des informations téléphoniques et des données de commande. L'invention concerne, également, un procédé et un appareil pour effectuer une transformation rapide de Fourier (FFT).
