Abstract

La présente invention a trait à un système de transmission/réception de diffusion numérique présentant une performance de réception améliorée et à son procédé de traitement de signaux. Un émetteur de diffusion numérique comporte un module de randomisation pour l'entrée d'un double flux de données de transport constitué de paquets robustes et normaux comprenant des multiplets de remplissage introduits dans les positions prédéterminées et pour la randomisation du double flux de transport; un échangeur de multiplets de remplissage pour le remplacement du multiplet de remplissage d'un flux de données randomisées par une donnée connue prédéterminée; et un codeur pour le codage de flux de données auquel les données connues sont introduites. Ainsi, la présente invention assure la détection de données connues à partir d'un signal reçu en provenance d'un côté réception et utilise les données connues détectées pour la synchronisation et l'égalisation, de sorte que la performance de réception de diffusion numérique peut être améliorée au niveau de canaux multivoies.
