In the application of the Huang Hilbert Transform (HHT) (or aka EMD, Empirical Mode Decomposition), there is the notable challenge of handling the edges (boundaries) of the signals; as noted in the answer link to its mention in other question.

What are some practical techniques that can be applied to signals in which there is 'noise' padding already present and when there is no redundant signal information at the boundaries? (eg how would a mirroring strategy be applied?)
