Design of two-channel linear-phase fir biorthogonal filter banks

Abstract

In the paper, a new method for the design of two-channel linear-phase biorthogonal FIR filter banks is presented. The method is based on the trade-off between obtaining the equiripple reconstruction error and satisfying other additional requirements. The filter bank design problem is solved by means of its transformation into an equivalent multicriterion optimization problem. Two design examples are given to illustrate the usefulness of the proposed technique.
