ECG signal is non-stationary, base line drift and power interference are the important factors influencing ECG signal extraction in high accuracy and directly determine the accuracy of ECG signal extraction and performance of analyzing and processing ECG signal. Adaptive filtering method can realize effective extraction of non-stationary signals without(More)
Waveforms and parameters in each segment of ECG signals reflect the activity state of the heart. The purpose of analyzing ECG signal is parameter extraction and waveform recognition, but power interference and base line drift seriously affect the accuracy of detecting ECG signal QRS waveform. On the basis of building an adaptive noise cancellation system(More)
