Abstract

Abstract

Prefiltering is indispensable for multiwavelet transforms. This paper proposes a prefilter with the length of l and an approximate order of 2 for GHM multi-wavelet, and proves that the order of prefilters for length 1 repeating signals cannot be or greater than 2 for GHM multi-wavelet, after analyzing the constructing ideas of various currently existing prefilters for GHM multi-wavelet.
