Do adapted wavelet transform methods improve the characterization of heart rate variability signals compared to short-term Fourier transform in normal subjects?
Adapted wavelet transforms provide a multi-scale approach to analyzing heart rate variability, allowing for different time windows for low- and high-frequency components.
Wiklund et al. (1997) studied this question.
