Wakefulness state estimation prior electroencephalography (EEG) measurements is important for more precise interpretation of those signals. Thus, a new method based on approximate entropy (ApEn) using a new range of ApEn parameter values was used to be compared with different spectral-based measures (i.e., relative delta subband power R.δ, relative theta sub-band power R.θ, power ratio between theta and alpha Pθ/α and power ratio between theta and beta Pθ/β) using occipital-alpha rhythm. The performances of the aforementioned measures were determined by using decision threshold value that satisfy the minimum misclassification rate between two groups: fully awake and light drowsy, where each of which was composed from 45 subjects. To determine the performance of the aforementioned measures, the results of the comparisons were based on cross validation method. Our results indicate that ApEn is better than R.δ, R.θ, Pθ/α and Pθ/β in evaluating wakefulness state with 9.24%, 6.57%, 10.25% and 4.74% respectively.
