Distinction non-stationary pulse wave signals with HHT method
In order to distinguish the difference of nonstationary pulse wave signals, the novel timefrequency analysis approach, i.e. Hilbert-Huang transform (HHT), is applied in this paper. First Hilbert-Huang transform is briefly introduced. Secondly, two differently non-stationary pulse wave signals are described in Empirical Mode Decomposition (EMD). With these results, the two pulse wave signals that looked apparently similar in time waves are distinctly different from each other. It is proved that HHT is effective for the purpose of distinction of non-stationary analysis.
