Using RBF and BP neural network processing EMD decomposition of end effects

On the analysis of empirical mode decomposition end effect appeared on the foundation of the reason,using BP and radial basis function neural network prediction method for the endpoint effect research.In the experiment,suppress the ending effect to inhibit end effect of EMD decomposed,by extending the signal sampling time.At the same time in order to compare two data extension method effect,respectively,will extend the data after EMD decomposition,which will extend the data after EMD decomposition.The experimental results show that,the two can effectively inhibit the endpoint effect on analysis results of impact,improved empirical mode decomposition effect.
