Este artigo propõe um novo controle de modo de adaptação (AMC) para um conjunto robusto de microfones adaptativos com uma matriz de bloqueio adaptativo (RAMA-ABM). O AMC proposto é baseado em correlações cruzadas de dois sinais de microfone e utiliza uma máquina de estados para controlar a adaptação para evitar o cancelamento do sinal alvo. A avaliação com dados sonoros obtidos em diferentes ambientes acústicos demonstra que a redução de ruído pelo AMC proposto é 3 dB melhor do que pelo AMC baseado na estimativa SNR. Testes de escuta subjetivos mostram que a qualidade do sinal de saída do AMC proposto é comparável ou até melhor do que a dos AMCs convencionais.

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.
