A QRD-RLS based frequency domain multichannel wiener filter algorithm for noise reduction in hearing aids

In this paper a frequency domain multichannel Wiener filter algorithm is proposed for noise reduction in hearing aids. It is shown that a robust and efficient QR Decomposition Recursive Least Squares (QRD-RLS) based updating scheme can be derived, if a single target speech source is assumed. Moreover, the scheme also allows to include a trade-off between… CONTINUE READING
