Abstract
A new method is proposed for the design of two-channel linear-phase perfect reconstruction QMF banks. The analysis lowpass filter is first designed by a conventional method, and then the synthesis lowpass filter is obtained by using a null-space projection approach. This method is then extended to the design of two-channel perfect reconstruction QMF banks with low reconstruction delay, which are desirable in some applications. Two design examples are given to illustrate the proposed methods
