Auscultation signals are nonstationary in nature.
Wavelet packet transform (WPT) has currently become a very useful tool in analyzing nonstationary signals.
Sample entropy (SampEn) has recently been proposed to act as a measurement for quantifying regularity and complexity of time series data.
WPT and SampEn were combined in this paper to analyze auscultation signals in traditional Chinese medicine (TCM).
SampEns for WPT coefficients were computed to quantify the signals from qi- and yin-deficient, as well as healthy, subjects.
The complexity of the signal can be evaluated with this scheme in different time-frequency resolutions.
First, the voice signals were decomposed into approximated and detailed WPT coefficients.
Then, SampEn values for approximated and detailed coefficients were calculated.
Finally, SampEn values with significant differences in the three kinds of samples were chosen as the feature parameters for the support vector machine to identify the three types of auscultation signals.
The recognition accuracy rates were higher than 90%.
