A new adaptive filtering subband algorithm for two-channel acoustic noise reduction and speech enhancement ?
We propose a new subband implementation of the Forward BSS algorithm. We propose a new two-channel criterion combination adapted to the proposed FBSS algorithm. The proposed FBSS algorithm is used to separate speech form noise and therefore enhance the speech signal intelligibility. The proposed algorithm improves the convergence speed of the cross adaptive filters which are used by the FBSS algorithm.
