Patent

CA 2655302

A digital broadcast system is disclosed. Most particularly, by inserting and transmitting predefined known data in a particular position within the data are having enhanced data transmitted therein, and by having a receiving system use the known data for demodulating and equalization processes, the receiving performance may be enhanced in an environment undergoing frequent channel changes and being vulnerable to noise.

L'invention concerne un système de télédiffusion numérique. Plus particulièrement, il est possible d'améliorer les performances de réception dans un environnement qui subit de fréquentes modifications des canaux et qui est vulnérable au bruit, en insérant et en transmettant des données connues prédéfinies dans une position particulière au sein des données, en y incluant des données améliorées, et en faisant en sorte que le système de réception utilise les données connues pour les processus de démodulation et d'égalisation.
