Abstract

Summary

One of the advantages which matching pursuit (MP) method has over conventional time-frequency decomposition is its ability to capture time-frequency fingerprint with extremely high resolution, which also makes itself quite sensitive to data noises and results in the non-uniqueness of its solution. Multichannel matching pursuit (MCMP) method has better performance and stability but still has some limitations. In this abstract, in addition to several previously proposed modifications, we make the parameter optimization process to extract difference phase values for different extracted atoms so that they can better match their corresponding traces. As a result, the whole decomposition process will have a significant reduction in both the extraction iterations and the extracted wavelets, which further offsets the anticipated time penalty. Moreover, because each extracted wavelet will contribute in the time-frequency spectrum, a smaller number of extracted wavelets will introduce less energy contamination into the final time-frequency spectrum.
