Cet article propose un annuleur de bruit adaptatif avec une faible distorsion du signal en présence de diaphonie. L'annuleur de bruit proposé comporte deux paires de filtres adaptatifs à couplage croisé, chacun étant constitué d'un filtre principal et d'un sous-filtre. Les rapports signal/bruit (SNR) des signaux primaires et de référence sont estimés par les sous-filtres. Pour réduire la distorsion du signal à la sortie de l'annuleur de bruit adaptatif, les tailles de pas pour l'adaptation des coefficients dans les filtres principaux sont contrôlées en fonction des SNR estimés. Les résultats de simulation informatique montrent que l'annuleur de bruit proposé réduit la distorsion du signal de sortie jusqu'à 15 dB par rapport à l'annuleur de bruit conventionnel.

Abstract: This paper proposes an adaptive noise canceller with low signal-distortion in the presence of crosstalk. The proposed noise canceller has two pairs of cross-coupled adaptive filters, each of which consists of the main filter and a sub filter. The signal-to-noise ratios (SNRs) of the primary and the reference signals are estimated by the sub filters. To reduce signal distortion at the output of the adaptive noise canceller, the step sizes for coefficient adaptation in the main filters are controlled according to the estimated SNRs. Computer simulation results show that the proposed noise canceller reduces signal distortion in the output signal by up to 15 dB compared to the conventional noise canceller.
