La technique de communication par lignes électriques (PLC) est une méthode permettant de réaliser des communications à haut débit dans un réseau domestique. Dans les canaux CPL, la qualité du signal de transmission est dégradée par le bruit coloré non gaussien ainsi que par la sélectivité en fréquence des canaux. Dans cet article, nous décrivons notre étude des performances d'un système OQAM-MCT dans lequel un annuleur de bruit est utilisé conjointement avec un égaliseur adaptatif par sous-porteuse dans le domaine temporel. De plus, nous proposons une méthode d'annulation du bruit conçue pour le système OQAM-MCT. Les performances du système OQAM-MCT sont évaluées dans les canaux PLC avec des réponses impulsionnelles mesurées en présence de bruit mesuré. Les résultats de simulation informatique montrent que le débit binaire du système OQAM-MCT est amélioré en utilisant à la fois un égaliseur adaptatif et un suppresseur de bruit, et que le système OQAM-MCT atteint de meilleures performances qu'un système OFDM avec une longueur d'intervalle de garde insuffisante.

Abstract: Power-line communication (PLC) technique is one method to realize high-speed communications in a home network. In PLC channels, the transmission signal quality is degraded by colored non-Gaussian noise as well as frequency-selectivity of the channels. In this paper, we describe our investigation of the performance of a OQAM-MCT system in which a noise canceller is used jointly with a time-domain per-subcarrier adaptive equalizer. Furthermore, we propose a noise cancellation method designed for the OQAM-MCT system. The performance of the OQAM-MCT system is evaluated in PLC channels with measured impulse responses in the presence of measured noise. Computer simulation results show that the bit rate of the OQAM-MCT system is improved using both an adaptive equalizer and noise canceller, and that the OQAM-MCT system achieves better performance than an OFDM system with an insufficient length of the guard interval.
