| Research Abstract |
We considered several mathematical problems, which occurs when we apply wavelet analysis, especially (continuous or discrete) wavelet transforms, and we make clear the basic properties of the transforms, and what applications can be made. Especially, we intensively considered such problems occuring from blind source separation (the problem to extract information about original signals from observed signals which are unknown mixtures of the original signals), and developped some new methods of blind source separation based on time-frequency analysis.
