Missing spectral decomposition methods.
Describe the solution you'd like
Add the rotated spectral PCA method from this paper. They use the continuous analytic Morlet wavelet as a robust estimator of the cross-spectral matrices instead of relying on the Hilbert transformed data, which improves frequency separation.
Describe alternatives you've considered
None.
Additional context
None.
