Abstract: Heart sound signal is a kind of typical nonstationary signal,so application is limited by a lot of traditional signal processing method. This paper puts forward using double adaptive lifting wavelet of heart sound signals denoising processing and extraction of heart sounds signal Teager-Huang boundary spectrum as characteristic parameters used for identity recognition. Double adaptive lifting wavelet ascension adopts adaptive update and adaptive prediction structure wavelet function,through the ... More
