An improvement for frequency-dominated fast matching pursuits algorithm

Chen Fayu Yang Changchun Information andTechnology Management Center,China National Coal Group Corporation,Beijing 100120,China  
Matching pursuits(MP)algorithm is a specific implementing method for signal self-adapted decomposition.With the prior- knowledge that the seismic signal is composed of certain limited fre- quency band,the frequency-dominated fast MP algorithm creates dictionary index which regards frequency as main matching target, so that it can decrease the amount of dictionary index size and itera- tion computation,and promote the efficiency and computation speed of signal MP decomposition.By taking the instantaneous fre- quency at the supreme points of complex seismic signal as original frequency and establishing the relation of linking frequency with scale parameters,the MP iteration process tightly relates with the effective attenuation of residual signal,which improves the perti nence for identifying original frequency.
