Patent

CA 2290580

There are provided channel encoding/decoding device and method to efficiently transmit/receive voice and data. Data with a low data rate or a short data frame is convolutionally encoded and data with a high data rate or a long data frame is turbo-encoded, thereby increasing encoding performance.

L'invention concerne un dispositif et un procédé de codage/décodage de canaux, permettant d'émettre/de recevoir efficacement des signaux vocaux ou des données. Les données transmises selon un faible débit ou une courte trame de données sont codées de manière convolutive, les données transmises selon un débit élevé ou une longue trame de données étant codées à vitesse turbo, ce qui améliore l'efficacité du codage.
