Adaptive Wavelet for Speech Coding


This paper presents a comparative study of adaptive wavelet clcisigii for a speech coder based on wavelet-type multires-oliit,iori t,ransforrns. It is concerned with the problem of c.lioosiug suitable transforms that are adapted to the given s l) c ~ ~ : l i signal in the sense t,hat they maximize the coding giiiii iit cach resolution level. Four adaptive… (More)
