Abstract

L’invention concerne la mise en place d’un nouveau schéma du turbo décodeurbasé sur le principe de la combinaison soft (dite en anglais << soft combining >>).Cette méthode permet d’améliorer la capacité de correction d’erreurs des turbo-codesen appliquant le principe de la combinaison soit aux résultats du décodage issus dechaque itération a1’intérieur du turbo-décodeur. L’évaluation des performances est faitepour l’algoritl1me de décodage turbo reposant sur le principe de max-log- maximum aposteriori (max-log-map), la modulation 16 quadrature amplitude modulation (16qam)et le canal de transmission a bruit blanc additif gaussien (bbag). Les résultats dessimulations montrent que les performances de la solution proposée sont meilleures quecelles de la solution conventionnelle. Nous nommons notre solution << soft combinedturbo codes >>.The invention relates to the introduction of a new scheme of the turbo decoder based on the principle of soft combining, which improves the turbo error correction capability. -codesen applying the principle of combining either the decoding results from each iteration inside the turbo-decoder. The performance evaluation is done for the turbo decoding algorithm based on the max-log-maximum aposteriori (max-log-map) principle, 16 quadrature amplitude modulation (16qam) and the additive white noise transmission channel. Gaussian (bbag). The results of the simulations show that the performance of the proposed solution is better than that of the conventional solution. We call our solution "soft combinedturbo codes".
