| 摘 要： | 介绍了一种微弱心电信号检测中降低肌电噪声的方法。采用神经网络对噪声进行白化预处理，然后用一种新方法提取掺杂在心电信号中的噪声作为自适应滤波的参考信号，其结果是使原始信号中的噪声得以降低，在晚电位检测的实验中得到了满意的结果。

| Abstract: | In this article, a new approach is introduced to lowering the myo electronic noise in weak ECG signals. We use artificial neural network to make the noise be white, and then we adopt an adaptive filter of which the reference signal is achieved by extracting from other ECG cycle. The outcome is the reduction of both white noise and non white noise in ECG signal. Satisfactory results have been achieved by using this method in the experiment of late potential detection. |
