Makalah ini mencadangkan kawalan mod penyesuaian (AMC) baharu untuk tatasusunan mikrofon penyesuaian yang teguh dengan matriks penyekat penyesuaian (RAMA-ABM). AMC yang dicadangkan adalah berdasarkan korelasi silang dua isyarat mikrofon dan menggunakan mesin keadaan untuk mengawal penyesuaian untuk mengelakkan pembatalan isyarat sasaran. Penilaian dengan data bunyi yang diperoleh dalam persekitaran akustik yang berbeza menunjukkan bahawa pengurangan hingar oleh AMC yang dicadangkan adalah 3 dB lebih baik daripada itu oleh AMC berdasarkan anggaran SNR. Ujian pendengaran subjektif menunjukkan bahawa kualiti isyarat keluaran oleh AMC yang dicadangkan adalah setanding atau lebih baik daripada kualiti isyarat keluaran AMC konvensional.

vol. E84-A, no. 2, pp. 406-413, February 2001, doi: .
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.
