| Abstract(in English) | The GSC (generalized sidelobe canceller), which is an adaptive microphone array, reduces noise under a condition where the target. sound is not degraded theoretically. Although the GSC is widely used because of its low computational cost, its noise reduction performance is low. In contrast, the AMNOR (adaptive microphone array for noise reduction) achieves high noise reduction performance by allowing a small amount of degradation of the target sound. Recently, attempts to increase the noise reduction performance of the GSC by allowing the degradation of the target sound have been made, among which the SP-SDR-MWF (spatially pre-processed speech distortion regularized multichannel Wiener filter)is representative example. Although the AMNOR and SP-SDR-MWF are both techniques for increasing the noise reduction performance while allowing the degradation of the target sound, the relationship between them has not yet been clarified. Here, we report a theoretical study of the relationship between these techniques. We then report experiments that were conducted to confirm the theoretical results. It is shown that these techniques achieve similar noise reduction performance when the same amount of degradation is allowed. |
