摘要
将LabVIEW和MATLAB强大的数值分析功能相结合,利用LabVIEW实现总体平均经验模态分解(Ensemble EmpiricalMode Decomposition,EEMD)信号处理方法,使得在信号分析时具有良好的人机界面;并且通过仿真与传统的经验模态分解(Empiri-cal Mode Decomposition,EMD)作比较,结果显示EEMD方法在信号分析中具有良好的抑制模态混叠问题,并且具有和MATLAB环境中相同的分解结果。
This article is aimed of combining the powerful numerical analysis capabilities of MATLAB with LabVIEW. Implement the signal processing method of ensemble empirical mode decomposition (EEMD) in LabVIEW, and make a good man--machine interface in the signal analysis. Meanwhile, compare with the traditional empirical mode decomposition by the simulation program. The results show that the EEMD inhibit the issue of mixed mode in the traditional Empirical Mode Decomposition. And it has the same results of decomposition within the MATLAB environment.
