NORSIG2000 Sample Paper

This paper propose the non-uniform subband scheme with combine acoustic echo canceller and noise reduction system. Bands of the presented multirate systems are spread according to the cochlear model by the all-pass transformation of polyphase filter bank. Oversampled approach was assumed for solution because of downsampling used, which reduce complexity with relation to full-band schemes, also adaptive algorithms used for acoustic echo cancellation converge faster, as well noise reduction algorithms operating on the signal compensated in cochlea spaced subband concern the acoustic environmental properties.
