Le codage vectoriel (VC) est un nouveau schéma de modulation vectorielle qui divise un canal SISO (Single-Input Single-Output) en sous-canaux orthogonaux par décomposition en valeurs singulières (SVD). Étant donné que les transmissions orthogonales permises par VC ne peuvent pas gérer les interférences inter-blocs (IBI) qui sont inévitables dans les canaux à étalement de retard, cet article propose un démodulateur d'annulation d'IBI qui peut supprimer l'IBI par une technique itérative. Nous montrons également que l'élimination de code dans laquelle les codes propres insignifiants avec les valeurs propres les plus basses sont intentionnellement supprimés des vecteurs de transmission réduit considérablement le BER (taux d'erreur sur les bits). Le VC qui utilise le démodulateur d'annulation IBI et l'élimination de code pour réduire le BER est comparé au VC d'origine non seulement dans les canaux SISO à étalement de retard, mais également dans les canaux MIMO (Multi-Input Multi-Output) à étalement de retard, tandis que l'accent est mis sur les cas MIMO. Les résultats de la simulation montrent que, sous un BER prédéterminé, le MIMO-VC amélioré peut améliorer le taux de transmission effectif par rapport à l'extension naturelle du VC pour retarder la propagation des canaux MIMO.

Abstract: Vector Coding (VC) is a novel vector modulation scheme that partitions a SISO (Single-Input Single-Output) channel into orthogonal subchannels by singular value decomposition (SVD). Because the orthogonal transmissions enabled by VC cannot cope with inter block interference (IBI) that is inevitable in delay spread channels, this paper proposes an IBI cancelling demodulator which can remove IBI by an iterative technique. We also show that code elimination in which insignificant eigencodes with lowermost eigenvalues are intentionally removed from transmission vectors greatly reduces BER (Bit Error Rate). The VC which utilizes the IBI cancelling demodulator and code elimination to reduce BER is compared with the original VC in not only delay spread SISO channels but also delay spread MIMO (Multi-Input Multi-Output) channels while emphasis is placed on the MIMO cases. Simulation results show that, under a predetermined BER, the enhanced MIMO-VC can improve effective transmission rate than the natural extension of VC to delay spread MIMO channels.
