Abstract

L'invention porte sur un système de transmission et de réception de radiodiffusion numérique et sur un procédé de traitement de signaux qui améliore la performance de réception du système. Un émetteur de radiodiffusion numérique peut comprendre un randomiseur pour recevoir et randomiser un flux de données dans une position spécifique dans laquelle sont insérés des octets de bourrage ; un échangeur d'octets de bourrage pour générer des données connues dans la position spécifique du flux de données dans laquelle sont insérés les octets de bourrage ; un codeur pour coder la sortie du flux de données de l'échangeur pour effectuer une correction d'erreur, et un modulateur et un convertisseur RF pour moduler le flux de données codées, effectuer une conversion RF du flux de données modulé et transmette les données ayant subi la conversion RF. Il est possible d'améliorer la performance de réception de diffusion numérique même dans un canal multivoie inférieur en détectant les données connues à la réception et un utilisant les données connues pour leur synchronisation et leur égalisation dans un récepteur de diffusion numérique.
