However, the solution is not unique and is also strongly affected by data noise. Multichannel matching pursuit (MCMP), exploiting lateral coherence as a constraint, might improve the uniqueness of the solution. It extracts a constituent wavelet that has an optimal correlation coefficient to neighboring traces, instead of to a single trace only. According to linearity theory, a wavelet shared by neighboring traces is the best match to the average of multiple traces, and therefore it might effectively suppress the data noise and stabilize the performance. It is found that the MCMP scheme greatly improves spatial continuity in decomposition and can generate a plausible time-frequency spectrum with high resolution for reservoir detection. 2010 01 01 2010 08 13 2010 V61 V66 10.1190/1.3462015 https://pubs.geoscienceworld.org/geophysics/article/75/4/V61/303300/Multichannel-matching-pursuit-for-seismic-trace https://pubs.geoscienceworld.org/seg/geophysics/article-pdf/75/4/V61/3223236/gsgpy_75_4_V61.pdf https://pubs.geoscienceworld.org/seg/geophysics/article-pdf/75/4/V61/3223236/gsgpy_75_4_V61.pdf http://geophysics.geoscienceworld.org/cgi/doi/10.1190/1.3462015 The Leading Edge Castagna 22 120 2003 10.1190/1.1559038 Instantaneous spectral analysis — Detection of low-frequency shadows associated with hydrocarbons Geophysics Chakraborty 60 1906 1995 10.1190/1.1443922 Frequency-time decomposition of seismic data using wavelet-based methods Journal of Neuroscience Methods Durka 148 49 2005 10.1016/j.jneumeth.2005.04.001 Multichannel matching pursuit and EEG inverse solutions Journal of the Institute of Electrical Engineers Gabor 93 429 1946 Theory of communication Geophysics Korneev 69 522 2004 10.1190/1.1707072 Seismic low-frequency effects in monitoring fluid-saturated reservoirs Mallat 2009 A wavelet tour of signal processing: The sparse way IEEE Transactions on Signal Processing Mallat 41 3397 1993 10.1109/78.258082 Matching pursuit with time-frequency dictionaries Geophysics Morlet 47 203 1982 10.1190/1.1441328 Wave propagation and sampling theory: Part I — Complex signal and scattering in multilayered media Geophysics Morlet 47 222 1982 10.1190/1.1441329 Wave propagation and sampling theory: Part II — Sampling theory and complex waves Geophysics Sinha 70 6 P19 2005 10.1190/1.2127113 Spectral decomposition of seismic data with continuous-wavelet transform Journal of Neuroscience Methods Studer 153 261 2006 10.1016/j.jneumeth.2005.11.006 From EEG dependency multichannel matching pursuit to sparse topographic EEG decomposition Geophysics Wang 72 1 V13 2007 10.1190/1.2387109 Seismic time-frequency spectral decomposition by matching pursuit
