在研究睡眠分期时,不少学者会使用光电容积脉搏波(PPG)信号作为研究对象,但在PPG采集过程中容易引入各种频率的噪声,影响后续睡眠分期特征的提取。为去除PPG信号噪声,提高生理参数特征计算的准确性,提出一种新的信号噪声处...展开更多 在研究睡眠分期时,不少学者会使用光电容积脉搏波(PPG)信号作为研究对象,但在PPG采集过程中容易引入各种频率的噪声,影响后续睡眠分期特征的提取。为去除PPG信号噪声,提高生理参数特征计算的准确性,提出一种新的信号噪声处理方法。采用AMPD改良算法识别波峰波谷,通过三次样条插值进行基线拟合,完成基线漂移的去除;以软硬阈值结合的小波变换完成肌电噪声的去除;以...
