基于非均匀B样条插值的EMD算法
EMD algorithm based on non-uniform B-spline interpolation
摘要
Abstract
Empirical mode decomposition (EMD) is a useful method in the nonlinear and non-stationary signal analysis. A novel EMD algorithm is proposed by non-uniform B-spline interpolation and solves the problem of incomplete signal decomposition effectively. Simulation results according to the same signal show that the new EMD algorithm is more suitable for the nonlinear and non-stationary signal. Different from the traditional algorithms, the non-uniform parameterization method has characteristics of high-precision and good-practical, which is conducive to promoting muhi-dimensional.关键词
