Abstract

In this article we present the first prototype of hardware implementation of the new modified turbo block decoder, where the termination of all the used soft-in-soft-out decoders is possible. We also enlighten the flexibility of the decoder and the application of same hardware in systems where different block lengths are used. Simulated and measured results in simple awgn channel and in median surroundings usingOfdm are presented.

Résumé

Cet article présente le premier prototype d’un circuit réalisant un turbo décodeur en bloc, pour lequel la terminaison des treillis de tous les decodeurs à entrée et sortie pondérées est possible. Il met aussi l’accent sur la flexibilité du décodeur et sur l’utilisation du même circuit pour des systèmes où des blocs de longueurs différentes sont utilisés. Les résultats obtenus par simulation el pur mesures sur un canal gaussien et dans l’environnement médian utilisant une modulationOfdm sont présentés.
