abstract = {According to the difference of time-frequency characteristics of ECG (electrocardiogram) signal and
jamming signal, FSWT (Frequency Slice Wavelet Transform) is used to deal with the ECG signal
denoising and feature extraction. FSWT algorithm has a good time-frequency aggregation and can freely
choose the frequency range for signal reconstruction to extract characteristic information flexibly and
accurately. Firstly, ECG signal is decomposed to get the whole time-frequency distribution characteristic
by using FSWT and carries on the detailed analysis. Frequency section interval is determined according
to frequency distribution characteristics of the jamming signal, disturbance signal is refactored and
isolated through the time-frequency filter and the inverse transformation of FSWT. So it can realize the
ECG signal denoising and feature extraction. The proposed algorithm is compared with wavelet threshold
denoising method, Empirical Mode Decomposition (EMD) and average empirical mode decomposition
(AIMF). The simulation results show that, the denoising effect of FSWT is superior to other methods
for ECG signal, and gives the time-frequency distribution characteristics of ECG signal.},
