Cet article propose un nouveau contrôle de mode d'adaptation (AMC) pour un réseau de microphones adaptatifs robustes avec une matrice de blocage adaptative (RAMA-ABM). L'AMC proposé est basé sur des corrélations croisées de deux signaux de microphone et utilise une machine à états pour contrôler l'adaptation afin d'éviter l'annulation du signal cible. L'évaluation avec des données sonores obtenues dans différents environnements acoustiques démontre que la réduction du bruit par l'AMC proposé est 3 dB meilleure que celle de l'AMC basée sur l'estimation du SNR. Les tests d'écoute subjectifs montrent que la qualité du signal de sortie de l'AMC proposé est comparable, voire meilleure, à celle des AMC conventionnels.

Abstract: This paper proposes a new adaptation-mode control (AMC) for a robust adaptive microphone array with an adaptive blocking matrix (RAMA-ABM). The proposed AMC is based on cross correlations of two microphone signals and uses a state machine for controlling the adaptation to avoid target-signal cancellation. Evaluation with sound data obtained in different acoustic environments demonstrates that the noise reduction by the proposed AMC is 3 dB better than that by the AMC based on the SNR estimate. Subjective listening tests show that the quality of the output signal by the proposed AMC is comparable to or even better than those by the conventional AMCs.
