MABWT may improve ECG denoising across noise conditions; leaves open clinical validation before practice adoption.
Sayadi et al. (2007) studied ECG noise and baseline wandering. Multiadaptive Bionic Wavelet Transform (MABWT) vs. Wavelet Transform (WT) was evaluated on Signal-to-Noise Ratio (SNR) improvement (dB) (1.69 dB). The multiadaptive bionic wavelet transform with soft thresholding improved the average signal-to-noise ratio of ECG signals by 1.69 dB compared to traditional wavelet transform methods.
