Patent

CA 2656976

A digital broadcast system is disclosed. More specifically, in the present invention, a transmitting system transmits known data having a pattern pre-decided by the protocol of the receiving system and the transmitting system. A receiving system uses the known data for performing carrier recovery and timing recovery, and for compensating of a phase change. Accordingly, the receiving performance of the receiving system may be enhanced in a situation undergoing severe and frequent channel changes.

L'invention concerne un système de diffusion numérique, et plus particulièrement un système de transmission qui transmet des données connues présentant un modèle prédéfini par un protocole du système de réception et du système de transmission. Le système de réception utilise les données connues pour exécuter une récupération de porteuse et de temporisation et pour compenser un déphasage. En conséquence, les performances de réception du système de réception peuvent être améliorées dans une situation de soumission à des changements de canal graves et fréquents.
