Patent

CA 2413890

A method and system for decoding is provided. In an aspect of the invention, an iterative method for decoding turbo codes utilizes a transformation of probability messages back and forth between formats, allowing for the probability messages to be updated using only summation operations, rather than a combination of summation and product operations, thereby offering the ability to reduce the amount of hardware and/or software resources for decoding.

L'invention concerne un procédé et un système de décodage. Selon un aspect, l'invention concerne un procédé itératif de décodage faisant appel à une transformation réciproque de messages de probabilité entre des formats qui permettent l'actualisation des messages de probabilité en question uniquement par des opérations de sommation, plutôt qu'en faisant appel à une combinaison d'opérations de sommation et de produit. On peut ainsi réduire la quantité de ressources de matériel et/ou de logiciel affectées au décodage.
