Dans cette lettre, nous proposons un nouveau schéma d'égalisation dans le domaine fréquentiel (FDE) pour les systèmes MIMO (à porteuse unique, entrées multiples et sorties multiples) sur des canaux variables dans le temps. Sur la base de l'égalisation par rétroaction de décision dans le domaine fréquentiel (FD-DFE), nous concevons un filtre anticipatif avec contrainte telle que l'égalisation puisse être facilement réalisée segment par segment à l'aide de la méthode de sauvegarde par chevauchement (OLS). Puisque la longueur du segment et la longueur du bloc peuvent être conçues indépendamment, notre proposition définit une longueur de segment relativement courte pour obtenir de bonnes performances dans des environnements variables dans le temps, et une longueur de bloc très longue pour obtenir une efficacité spectrale élevée. De plus, nous présentons deux scénarios dans la conception de filtres pour les systèmes MIMO.

Abstract: In this letter, we propose a novel frequency-domain equalization (FDE) scheme for single-carrier multiple-input multiple-output (MIMO) systems over time-varying channels. Based on frequency-domain decision-feedback equalization (FD-DFE), we design a feedforward filter with constraint such that the equalization can be easily realized segment-by-segment with the help of the overlap-save (OLS) method. Since the segment length and block length can be designed independently, our proposal sets relatively short segment length to obtain good performance in time-varying environments, and very long block length to achieve high spectral efficiency. Furthermore, we present two scenarios in the design of filters for MIMO systems.
