| Abstract: | Analysis of sleep staging is very important work in knowing process of sleep electro-encephalon activity.The rule of sleep stage classification was introduced.And after comparing several kinds of classic methods of time-frequency analysis,multi-resolution time-frequency analysis based on wavelet packet transform and short-time Fourier transform was used to realize the analysis of sleep stage classification automatically.The experiments,done on virtual EEG instrument,show that good results of sleep stage classification can be obtained by this method. |
