Application of High-Order Statistics in Seismic Signal Analysis
Qin Xue-fei · Journal of Jilin University · 2007
High-order statistics analysis is in front of domestic and international signal processing realm nearly twenty years,is applied to all problem that need to be considered as non-gauss,non-minimum phase,non-linear and circular stationary.In the seismic signal process realm,high-order statistics can be used to eliminate color noise,identify and estimate non-minimum phase wavelet.Independent component analysis based on high-order statistics has become the hotspot of signal processing realm and have been applied in seismic signal analysis.The definitions and properties of HOS and the high-order statistical time-frequency analysis are introduced in this thesis.And we use this theory to do some simulation tests and real seismic data tests.
