Disposal of Boundary Problem in EMD Method Applying RBF Neural Network

QU Wei-lian~1 CHENG Lei~1(1.Hubei Key Laboratory of Roadway Bridge & Structure Eng.,WUT,Wuhan 430070,China)  
This paper extends two sides of a given data series using RBF neural network analysis method,then receives two additive maximum points and minimum points separately,next,connects the additive extremum points and extremum points of the original time series utilizing cubic spline function.In this way,the super and infra wrapping lines are drawn up and have achieved the exact EMD decomposition,which settle its boundary problem preferably.
