In this paper, the principles of the Discrete Wavelet Transform and Stationary Wavelet Transform denoising are discussed . Selection rules of thresholding value and the thresholding operations are analyed. Discrete Wavelet Transform and Stationary Wavelet Transform are used to denoise the ECG signal , the results are compared with different thresholding values and different thresholding operations. The experiment results show that Stationary Wavelet Transform is obviously better than Discrete Wavelet Transform,not...
