Abstract:
The nonlinear wavelet method is used to detect ECG signal. The ECG signal disrupted by high-frequency noise is decomposed with a dyadic Daubechies wavelet according to Mallat algorithm. The principle of the nonlinear wavelet detection method is discussed. Along with the Lipschitz criterion, it is applied to denoising the disrupted ECG signal. The ECG signal is effectively recovered while denoised.
