CHARACTERIZATION OF ORTHONORMAL HIGH-ORDER BALANCED MULTIWAVELETS IN TERMS OF MOMENTS

In this paper, we derive a characterization of orthonormal balanced multiwavelets of order p in terms of the continuous moments of the multiscaling function phi. As a result, the continuous moments satisfy the discrete polynomial preserving properties of order p (or degree p-1) for orthonormal balanced multiwavelets. We derive polynomial reproduction formula of degree p-1 in terms of continuous moments for orthonormal balanced multiwavelets of order p. Balancing of order p implies that the series of scaling functions with the discrete-time monomials as expansion coefficients is a polynomial of degree p-1. We derive an algorithm for computing the polynomial of degree p-1.
