APPLICATION OF HOMOMORPHIC SYSTEM CONCEPT IN SEISMIC DATA PROCESSING
(Abstract)
A concise background in homomorphic systems is presented, the particular
case of convolutional homomorphic systems is analysed in detail, followed by
the introduction of a complex cepstrum concept and presentation of phase unwrapping
problem and its solutions. Finally, an algorithm for wavelet estimation by
log spectral averaging is described and a computer simulation is performed.
Key words: homomorphic system, wavelet estimation, complex cepstrum, phase
unwrapping log spectral averaging.
