Abstract
(EN)
When transmitted, packet data is combined with a synchronizing pattern of q words (q = m + n) which consist of a combination of a fixed m-word pattern (m is an integer equal to or greater than 1) and a plurality of variable n-word patterns (n is an integer equal to or greater than 2). The variable patterns included in at least two consecutive packets have different bit configurations.
(FR)
Lorsqu'elles sont émises, des données organisées en paquets sont combinées à un modèle de synchronisation de q mots (q = m + n) qui est constitué d'une combinaison d'un modèle fixe à m mots (m est un entier supérieur ou égal à 1) et une pluralité de modèles variables à n mots (n est un entier supérieur ou égal à 2). Les modèles variables contenus dans au moins deux paquets consécutifs ont des configurations binaires différentes.
