摘要：
A method that is using adaptive lifting wavelet transform to pre-processing the heart sounds by constructing its predict-filter and update-filter is proposed in the paper. The lifting wavelet transform retained the advantage of normal wavelet transform in signal processing, and improved the speed of signal processing, so this method has good application in the de-noising of heart sounds' real time processing. Many heart sound data are used in the experiment, the conclusion is that the method has very good application foreground in the portable heart sounds collection and analysis instruments.
