Abstract
In this paper, a new technique for designing linear phase QMF filters is proposed. These filters have the frequency responses of sharp and symmetrical transition charcteristics, and the capabilities of perfect reconstruction and simple implementation. By applying video signals into basic sub-band systems, the performances between designed QMF pair and other QMF pairs1,2 are compared in alias-cancellation!reconstruction errors and Peek Signal- to-Noise Ratios(PSNRs). It is shown that the proposed QMF pair has better performance than the short kernel filter pair1, and similar performance as the long kernel filter pair2.
