提出一种利用小波包变换逼近信号消除心电图ECG基线漂移噪声的方法。该方法的基本思想是：通过对 ECG信号进行多分辨率分析，利用所得到的一段或几段逼近信号充分逼近ECG信号中的基线漂移噪声的特性，从而 消除某线漂移分景。-Presents a wavelet packet transform approximation signal method to eliminate electrocardiogram ECG baseline drift noise. The basic idea

Abstract— with the latest advancements in electronics, several techniques are used for removal of unwanted entities from signals especially that are implied in the most sophisticated applications. The removal of power line interference from m

以离散平稳小波变换的心电信号噪声去除方法为基础，根据噪声的不同来源及其频带分布特点，对变换后的细节信号采用不同的阈值去噪方案。并提出一种基于准则原理的阈值选取方法。经国际标准数据库中验证，试验表明，该方法行之有效-With discrete stationary wavelet transform of ecg signal to noise removal method as the foundation, according to the different sources of noise
