Application on LMD in Pulse Signal Analysis Based on Mathematical Morphology
WANG Li
Abstract：The pulse signal was a very weak physiological signal and it was susceptible to external noise interference in the col?lection process. In order to remove noise and improve the efficiency of pulse signal decomposition,this paper proposed a local mean decomposition method based on mathematical morphology. The simulation results show that the improved LMD decomposition can ef?fectively remove the noise,and also can improve the efficiency of local mean decomposition.
