Abstract
(EN)
The reception(102) reception unit includes; a first processing unit processing a first signal received from a source channel, and including a filtering unit to filter said first signal in digital domain, and extract unit to extract a information from said first signal; a second processing unit processing a second signal received from a destination channel, and said source channel and said destination channel are distinct each other; a third processing unit providing said information extracted from said first signal to said second signal said third processing unit executes; providing said information from said first processing unit to said second processing unit using information lanes of a clock rate strictly lower than a symbol rate of said second signal, a monitoring unit to generate a monitor signal according to the quality of said second signal; and a control unit controlling a skew between said first signal and said second signal in a bandwidth of said filtering units in said first processing unit.
(FR)
L'unité de réception (102) selon l'invention comprend les étapes suivantes : une première unité de traitement traite un premier signal reçu à partir d'un canal source, et comportant une unité de filtrage destinée à filtrer ledit premier signal dans le domaine numérique, et une unité d'extraction destinée à extraire des informations à partir dudit premier signal ; une deuxième unité de traitement traite un deuxième signal reçu à partir d'un canal de destination, et ledit canal source et ledit canal de destination étant distincts l'un de l'autre ; une troisième unité de traitement fournit lesdites informations extraites à partir dudit premier signal audit deuxième signal que ladite troisième unité de traitement exécute ; fournir lesdites informations depuis ladite première unité de traitement à ladite deuxième unité de traitement en utilisant des voies d'informations d'un taux d'horloge strictement inférieur à un taux de symbole dudit deuxième signal, une unité de contrôle destinée à générer un signal de contrôle selon la qualité dudit deuxième signal ; et une unité de commande commandant un retard de propagation entre ledit premier signal et ledit deuxième signal dans une bande passante desdites unités de filtrage dans ladite première unité de traitement.
