Cette lettre propose deux schémas efficaces de détection par retour de décision (DF) pour le code de bloc spatio-temporel (STBC) sur des canaux à évanouissement sélectif dans le temps. La détection DF existante provoque une propagation d'erreur lorsque le premier symbole n'est pas détecté correctement. Cependant, les schémas de détection proposés fournissent deux candidats en fonction d'un gain de canal ou d'une règle de sélection basée sur le rapport de vraisemblance (LLR) moyen et choisissent un meilleur candidat pour le premier symbole. Les résultats de simulation montrent que les schémas de détection proposés réduisent la propagation des erreurs et génèrent un gain de rapport signal/bruit (SNR) significatif avec une complexité modérée, par rapport au schéma de détection DF existant.

Abstract: This letter proposes two efficient decision-feedback (DF) detection schemes for space-time block code (STBC) over time-selective fading channels. The existing DF detection causes error propagation when the first symbol is not detected correctly. However, the proposed detection schemes provide two candidates according to a channel gain or an average log-likelihood ratio (LLR) based selection rule and choose a better candidate for the first symbol. Simulation results show that the proposed detection schemes reduce error propagation and yield significant signal-to-noise ratio (SNR) gain with moderate complexity, compared to the existing DF detection scheme.
