| Abstract: | A novel EMD algorithm is proposed based on Shepard method.From the mathematical point of view to explain the reasons for the selection of the algorithm by introducing Shepard method with its properties.At last,simulation on a noisy signal is presented to show the EMD algorithm is suitable for the nonlinear and non-stationary signal |
