An Application of Wavelet Package Analysis to the Signal Compression

YANG Chao, XU Zeyin, LU Yurong( Chengdu University of Technology,Chengdu 610059, China )  
Wavelet package analysis has been rapidly developed based on wavelet transform in recent years. Signal was expressed as a linear combination of a set of best bases of wavelet package, the energy of expansion coefficients are concentrated in a small number of coefficient because of the good location properties of wavelet package best bases. So it is possible to achieve high compression ratios without any loss of useful and important information of the compressed signal. Owing to the limitation of wavelet transform, the authors of this paper have researched wavelet package analysis in the signal compression and given some experimental verifications.
