Abstract

Un signal numérique à bande large est divisée en une pluralité de sous-signaux par démultiplexage, chacun desdits sous-signaux ayant un débit binaire inférieur à celui du signal de bande large, et étant réparti et transmis dans son sous-canal respectif (16 à 11), tel que par exemple, des canaux téléphoniques numériques ordinaires ayant des temps de propagation arbitraires. Les différences de temps de propagation sont compensées par transmission d'au moins un drapeau dans chaque sous-canal au lancement, et par retardement individuel des signaux reçus dans le récepteur, en réponse aux drapeaux reçus de sorte que l'on peut reconstituer le signal à bande large à partir des sous-signaux par multiplexage. Ce lancement automatique ne nécessite aucun chemin de signal de retour et l'on insère une temporisation minimale afin de permettre le rétablissement dudit signal à bande large.
