We describe a method to suppress maternal and noise contaminations in single-lead fetal ECG recordings. A nonlinear state space projection technique originally developed for noise reduction in deterministically chaotic signals is used. The method is successfully applied to recordings with fetal components and noise of comparable amplitude.
我们描述了一种抑制单导联胎儿心电图记录中母体和噪声干扰的方法。使用了一种最初为确定性混沌信号降噪而开发的非线性状态空间投影技术。该方法已成功应用于具有幅度相当的胎儿成分和噪声的记录。
