Cet article propose un nouveau système MIMO qui introduit un schéma de flux hétérogène (HTS) et une méthode de détection de signal aveugle pour les communications radio mobiles. Le schéma HTS utilise différentes méthodes de modulation ou de codage pour différents flux MIMO, et la méthode de détection aveugle ne nécessite aucune séquence d'entraînement pour la séparation des signaux, la détection et l'estimation du canal. Le schéma HTS peut lever l'ambiguïté liée à l'identification de flux séparés sans mots uniques nécessaires à la détection aveugle MIMO conventionnelle. Plus spécifiquement, deux exemples de HTS sont considérés : le type de modulation HTS (MHTS) et le type de décalage temporel (THTS). Le MHTS, qui utilise différentes constellations de modulation avec la même bande passante pour différents flux, a déjà été étudié. Cet article propose un THTS qui utilise différents timings de transmission avec la même modulation. THTS peut rendre la détection aveugle plus robuste et efficace avec un échantillonnage fractionné. Le traitement conjoint aveugle de la détection et de l'estimation de canal effectue un MIMO-MLSE aveugle adaptatif et est dérivé d'un égaliseur MLSE aveugle adaptatif qui utilise l'estimation de canal récursive avec l'inverse généralisé de Moore-Penrose. Les simulations informatiques montrent que le système proposé peut atteindre des performances BER supérieures avec Eb/N0 dégradation de 1 dB en THTS et de 2.5 dB en MHTS par rapport à la détection idéale par maximum de vraisemblance.

Abstract: This paper proposes a novel MIMO system that introduces a heterogeneous stream (HTS) scheme and a blind signal detection method for mobile radio communications. The HTS scheme utilizes different modulation or coding methods for different MIMO streams, and the blind detection method requires no training sequences for signal separation, detection, and channel estimation. The HTS scheme can remove the ambiguity in identifying separated streams without unique words that are necessary in conventional MIMO blind detection. More specifically, two examples of HTS are considered: modulation type HTS (MHTS) and timing-offset type HTS (THTS). MHTS, which utilizes different modulation constellations with the same bandwidth for different streams, has been previously investigated. This paper proposes THTS which utilizes different transmission timing with the same modulation. THTS can make the blind detection more robust and effective with fractional sampling. The blind joint processing of detection and channel estimation performs adaptive blind MIMO-MLSE and is derived from an adaptive blind MLSE equalizer that employs the recursive channel estimation with the Moore-Penrose generalized inverse. Computer simulations show that the proposed system can achieve superior BER performance with Eb/N0 degradation of 1 dB in THTS and 2.5 dB in MHTS compared with the ideal maximum likelihood detection.
