Original Abstract

At present these are several structures which can realize quadrature mirror filter bank. For example it can be realized directly or by lifting algorithm. Majority of realization solve computing complexity. The structure designed in this paper has higher computing complexity, but it is focused on better suppressing of distortion of subband signals. For this purpose the sigma-delta modulators are in decomposition part of quadrature mirror filter bank which have different transfer for input signal and for distortion signal. The transfer function of distortion signals can be chosen by their suitable design.
