| 摘 要： | 经验模态分解方法（EMD）在非平稳信号的分析和处理中起着重要的作用，为了能够方便的使用EMD方法对信号进行处理，现将LabVIEW虚拟仪器开发平台良好的用户图形界面和MATLAB软件强大的数值分析功能相结合,利用LabVIEW调用MATLAB实现EMD信号处理方法。仿真结果表明对信号进行EMD分解后，使得瞬时频率具有了物理意义，但只是对信号进行了初步处理，可根据实际需要进行相应后续处理。

| Abstract: | Empirical mode decomposition is an important method for analyzing non-stationary signal. LabVIEW virtual instrument is perfect in computer-user graphical interfaces while MATLAB software has powerful compute ability to call MATLAB to realize EMD analysis in LabVIEW. The two are combined to make EMD processing convenient. The simulation result indicates that the EMD analysis makes instantaneous frequency physically significant, but it is only the beginning of processing and can be improved according to the requirement. |
