ECG Signal Extraction Method Based on EMD Decomposition
Objective
An ECG signal extraction technique combining wavelet and singular value decomposition aims to reduce noise. Singular values guide reconstruction, and wavelet thresholding denoises to achieve a cleaner signal.
Abstract
In order to minimise noise in the obtained ECG signal, a wavelet and singular value selection based approach for ECG signal extraction is presented. The singular value decomposition on the ECG signal is the initial step towards obtaining the ECG signal component corresponding to each singular value. Next, using the signal component corresponding to the greatest singular value, cross-correlation coefficients between the signal component and other components are calculated. The cumulative contribution rate of singular values is added to determine the number of singular values for ECG signal reconstruction. The wavelet threshold de-noising approach is used to de-noise the final determined signal components. The process of reassembling the signal's constituent parts ultimately produces the de-noising ECG signal. In comparison to the wavelet threshold approach, the experimental findings demonstrate that the method has a good noise reduction effect and can efficiently suppress noise and extract signal.
