Les turbocodes spatio-temporels présentent à la fois les avantages des codes spatio-temporels et des turbocodes, et le turbocode spatio-temporel proposé par Su et Geraniotis est connu pour atteindre un taux de codage complet et une diversité d'antennes complète. Cet article présente quelques améliorations de leur turbocode spatio-temporel dans une configuration à deux antennes. Nous proposons d’abord une nouvelle condition pour une diversité d’antenne complète qui impose moins de contraintes à l’entrelaceur. Ensuite, en appliquant une méthode utilisée pour améliorer la modulation turbo codée en treillis au turbocode espace-temps, nous proposons un nouvel algorithme de décodage qui utilise des estimations plus précises sur les informations extrinsèques. Les résultats de simulation montrent que la condition proposée garantit une diversité d'antennes complète et que le nouvel algorithme de décodage offre de meilleures performances que celles de Su et Geraniotis.

Abstract: Space-time turbo codes have both advantages of space-time codes and turbo codes, and the space-time turbo code proposed by Su and Geraniotis is known to achieve full coding rate and full antenna diversity. This paper presents some improvements of their space-time turbo code in a two-antenna configuration. We first propose a new condition for full antenna diversity which imposes less constraints on the interleaver. Next, by applying a method used to improve turbo trellis-coded modulation to the space-time turbo code, we propose a new decoding algorithm which utilizes more precise estimates on extrinsic information. Simulation results show that the proposed condition assures full antenna diversity and the new decoding algorithm provides a better performance than that of Su and Geraniotis'.
