胎儿心电信号的提取对孕期胎儿健康状况的检测具有重要意义。本文提出一种基于平稳小波变换的单/多通道胎儿心电提取方法。多通道环境下输入信号包括腹部混合信号和母体心电信号，单通道环境下母体心电信号采用对腹部混合信号进行窗口平均法获得，然后对信号进行平稳小波变换与阈值去噪，继而提取胎儿心电信号。PhysioNet数据测试实验表明，该方法在单/多通道的环境下均能成功提取到清晰的胎儿心电信号，并且能有效地消除噪声。

Fetal electrocardiogram (ECG) signal extraction is of great significance to the detection of fetal health status in pregnancy. Here, we propose a single/multi-channel fetal ECG extraction method based on stationary wavelet transform. In the multi-channel environment, the input signals include the abdominal mixed signals and the maternal ECG signals. In the single-channel environment, the abdominal mixed signals are processed with window averaging method for obtaining maternal ECG signals, and then, the obtained maternal ECG signals were processed with stationary wavelet transform and threshold denoising to extract fetal ECG signals. PhysioNet data test shows that the proposed method can successfully extract the clear fetal ECG signals in single/multi-channel environment and effectively eliminate noise.
