基于Matlab的心电信号去噪

Electrocardiogram (ECG) signals are very weak and low-frequency biological signals that are easily affected by noise inside and outside the body. Through the analysis of the generation mechanism and characteristics of ECG signals, wavelet transform and empirical mode decomposition are used to eliminate noise interference in ECG signals. Parameters such as signal-to-noise ratio, mean square error, and autocorrelation coefficient are analyzed during the denoising process to evaluate the denoising effect of different methods. Simultaneously design a graphical user interface (GUI) to simulate and demonstrate the implementation of an electrocardiogram signal denoising system.
