Improved subband-forward algorithm for acoustic noise reduction and speech quality enhancement

- We propose a new subband implementation of the Forward BSS algorithm.
- We proposed a new two-channel variable step-size techniques adapted to the proposed FBSS algorithm.
- The new FBSS algorithm is used to separate speech form noise and therefore enhance the speech signal intelligibility.
- The new algorithm improves the steady state values of the cross adaptive filters which are used by the FBSS algorithm.
