| 摘 要： | 为了将经验模态分解(empirical mode decomposition,简称EMD)用于在线信号处理,提出了实时EMD实现方法,即重叠处理-均值继承经验模态分解.该方法通过信号分段、重叠处理、均值继承和中点拼接等技术,实现了对在线信号的动态、连续、快速和高精度处理.仿真信号和实际测试信号算例验证了该方法的可行性和有效性.

| Abstract: | For using empirical mode decomposition(EMD) to process on-line signal,a suit of rounded realization methods of real-time EMD is developed,which can dynamically,continuously,fast and precisely process on-line signal with the technology of signal-subsection,superposition-process,mean-inheriting and middle point-scrabbling.Some examples of simulated signal and test signal validate the feasibility and validity of the methods. |
