Noise reduction algorithm in ECG signals using wavelet transform
IEEEProceedings of the 1998 2nd International Conference on Biomedical Engineering Days -- 20 May 1998 through 22 May 1998 -- Istanbul, Turkey -- 49112A noise reduction algorithm based on multi-resolution orthogonal wavelet transform in ECG signals is discussed. The results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley and Daubechies for two different noise characteristics. The first one is artificially obtained line interference sinusoidal noise and the second one is uniformly distributed random noise or white noise. The results show that the former noise is completely eliminated from the signal by using both of the filter coefficients. However, the latter noise did not give the same performance as that of the former one
