  • Abstract
    The author presents a self-adapting noise reduction system which is based on a 4-microphone array combined with an adaptive Wiener filter. The LMS algorithm is used for adaptation. This filtering structure allows a simple implementation in the time domain on a sample-by-sample basis.
