Hi,
Does anyone know how to do Cross-wavelet analysis with pipo wavelet?
Thanks,
Shai
interesting question. Can you elaborate?
Dear Diemo Schwarz,
I want to measure synchrony using cross wavelet coherence.
As I understand “Cross wavelet coherence” is calculated by first applying a wavelet transform to each of the signals being compared, combining these to create the cross-wavelet transform (by multiplication of one transform with the complex conjugate of the other), and finally converting this into a coherence spectrogram.
The spectrogram charts coherence at different sized frequency bands (corresponding to wavelet scales) across time, with values ranging from 0 (uncorrelated) to 1 (correlated).
By averaging the spectrogram over a set time period, a response can be obtained for that time period which charts the frequencies at which the two signals are coordinated
