Method of empirical modes and wavelet­filtering: application in geophysical problems

Theoretical bases of empirical mode decomposition being one of the new methods of time-frequency analysis of processes with time-varying characteristics are discussed. It is shown that application of this approach together with wavelet-filtering allows one to study in details the structure of multicomponent registered signals recorded in prospecting seismology.

Progress and prospect of wavelet transform application to the analysis of nonstationary nonlinear dates in contemporary geophysics

The presented paper is an analytical review of the methods and examples of applications of the continuous and discrete wavelet transform in geophysical study. The possibility of the extension of application of the wavelet-based methods in geophysics is also considered.
