WebJan 6, 2024 · The cross-wavelet power, which reveals the regions (in time-frequency plane) of common power, is the absolute value of the cross-wavelet transform above. And similar to the definition of coherence, one can define wavelet coherence as, where s and n denote the wavelet scale (which is related to frequency) and time index respectively. WebDoubechies wavelet transform acts almost similar to Haar wavelets. Regardless to the similarities between these signals in computing running averages and differences via scalar products with scaling signal and wavelets, there is a slight difference between these signals and that refers to scaling signal and wavelets definition.
