L'algorithme de Viterbi à sortie souple vers l'arrière (un SOVA vers l'arrière) est comparé au SOVA conventionnel (un SOVA vers l'avant) dans le décodage de code turbo. Nous constatons une amélioration notable des performances du SOVA arrière lorsqu'il n'est pas terminé, ce qui s'avère être dû à une valeur de fiabilité plus petite, indiquant que les conditions de terminaison du turbo-encodeur affectent fortement les performances du décodeur SOVA arrière. Nous proposons également un décodeur SOVA mixte en série efficace sur le plan matériel, composé d'un décodeur SOVA aller et d'un décodeur SOVA arrière. Les résultats de simulation montrent que le décodeur SOVA mixte en série proposé présente un gain de codage de 0.2 dB à 2.0 dB. Eb/No sur le SOVA avant pour un exemple typique de code turbo.

Abstract: The backward direction Soft Output Viterbi Algorithm (a backward SOVA) is compared with the conventional SOVA (a forward SOVA) in turbo code decoding. We find noticeable performance improvement for the backward SOVA when it is not terminated, which turns out to be due to a smaller reliability value, indicating that the termination conditions of the turbo encoder strongly affect the performance of the backward SOVA decoder. We also propose a hardware efficient serially mixed SOVA decoder composed of a forward SOVA decoder and a backward SOVA decoder. Simulation results show that the proposed serially mixed SOVA decoder has a 0.2 dB coding gain at 2.0 dB Eb/No over the forward SOVA for a typical turbo code example.
