Sleep Quality Analysis Based on HHT
This paper introduces a method to estimate sleep quality via EEG analysis based on HHT. Sleep stages were classified throughout the method where instantaneous frequencies of sleep EEG with physical meaning and energy frequency distribution are used as feature parameters for each stage computed with the HHT. Meanwhile, the well known psychological test called PSQI was carried out for comparison. The experimental results showed that the EEG analysis based on HHT is promising for objective evaluation of sleep quality comparable to PSQI.
