摘    要:希尔伯特-黄变换(Hilbert-Huang Transform,简称HHT)是上世纪末出现的一种处理非线性非平稳信号的新方法 ,EMD边界处理是其中的关键技术之一。着重介绍了一种基于本征波匹配的EMD边界处理方法——本证波匹配预测法,特别是介绍了将该方法和其他两种有代表性的EMD边界处理方法应用于仿真信号和和实测信号的算例对比,从而验证了本证波匹配预测法的先进性。本文工作使得相关研究得到较大程度地深化和完善。

关 键 词:HHT    EMD边界处理    本证波    本证波匹配预测法

Abstract:Hilbert-Huang transformation(HHT) has been a new method for processing non-linear and non-stationary signals since the end of the 20th century.Meanwhile,boundary processing is one of its key technologies.A method for EMD boundary processing based on intrinsic wave matching called intrinsic wave matching prediction method was proposed here.Especially,the comparison between two representative EMD boundary processing methods and the proposed method was introduced in processing simulated signals and tested signals.The effectiveness of the proposed method was validated.
Keywords:HHT  EMD boundary processing  intrinsic wave  intrinsic wave matching prediction method
