| 摘要: |
| 提出了一种基于掩膜信号法的端点延拓新方法,可以有效地解决产生于希尔伯特-黄变换中的端点效应;对信号进行外延后进行EMD,然后利用掩膜信号对IMF分量进行延拓后再进行希尔伯特变换;仿真实验证实了该方法的有效性。 |

| Abstract: |
| This paper gives a new extending method based on the masking signal.It can effectively restrain the end effect produced in Hilbert-Huang.We extend the data before using EMD,and then we extend the IMF based on making signal before using Hilbert transformation.Simulation and experiment reuslts proved its effectiveness. |
