摘要:
 提出一种基于Hilbert-Huang变换的脉率变异性信号(PRV)提取方法。首先对脉搏信号进行经验模态分解,得到脉搏信号的内禀模态函数及其边际谱;然后,根据边际谱的频率范围选取能反映脉率变化的内禀模态函数分量;最后,从分量中提取PRV信号。将所提出的方法应用于实际采集的脉搏信号,结果表明所提出的方法能从脉搏信号中准确地提取PRV信号,并且抗噪性很强。
Abstract:
 A novel method based on Hilbert-Huang transform for extracting pulse rate variability (PRV) signals is proposed in this study. The pulse signals are firstly decomposed by empirical mode decomposition to obtain the intrinsic mode functions of pulse signals and their marginal spectra. According to the frequency range of the obtained marginal spectra, the intrinsic mode functions components which can reflect the change of the pulse rate are selected, and the PRV signals are extracted from those components. The proposed method is applied into the actual pulse signal acquisition, and the results show that the proposed method can accurately extract the PRV signals from the pulse signals and has a good anti-noise performance.
