Abstract

A new family of two-channel low-delay filter banks and wavelet bases using the PR structure of Phoong, Kim and Vaidyanathan (1995) with sum of powers-of-Two (SOPOT) coefficients are proposed. In particular, the functions alpha(z) and beta(z) in the structure are chosen as nonlinear-phase FIR and IIR filters, and the design of such multiplier-less filter banks is performed using the genetic algorithm. The proposed design method is very simple to use, and is sufficiently general to construct low-delay filter banks with flexible lengths, delays, and regularity. Several design examples are given to demonstrate the usefulness of the proposed method.
