Development of an algorithm to study the instantaneous coherence between two non-stationary signals using a time-frequency analysis methods, the hilbert-huang transform (using the EEMD - ensemble empirical mode decomposition - approach). This algorithm should receive as input two signals (each with two colummns, the first being the time, the second the scalar) and should output a 2d colour coherence spectra, color coded and with X being the time and Y the "frequency". Should be developed either in matlab or in python. Regards,

As per Heisenberg uncertainty, if you increase resolution in time, you loose resolution in frequency i.e. ,∆x*∆v >h/4π, which means to localise in time for 2 non-stationary signals, there has to be a trade-off. Yes, you're correct that wavelets solved this problem linearly. HHT As per your proposal, it will be great to see if your hypothesis stands true. I've known Hilbert Huang transform in other domain, i.e. in image compression. So, if you have 1 D signals, it should be just one dimensionality lower. And, hence should be specific case of it. The MATLAB is a better tool for a rough draft, that can later be extended if required. This is also suitable for hypothesis testing. EEMD I've had the chance to read the papers of Zu et al 2005, 2009 regarding their approach to noise based signal analysis in them. However, I've not been aware of any libraries been implemented for specifically that purpose. This is highly mathematical and needs linear algebra libraries for optimization. Basically, an average is calculated by shifting a AWGN filter over the signal, where after many iterations only the original component of the signal is left. Both HH and EEMD help in spatio-temporal analysis. Approach: 1st : Derive the psudo code in pen and paper, and get verified 2nd : Test in MATLAB/ Octave Kindly message me whenever you're free. If not online, shall reply ASAP. Thank you!
