In this paper, EEG (electroencephalogram) signals are processed by HHT (Hilbert-Huang Transform). First, a new de-noising method is employed to smooth the EEG signals based on EMD (Empirical Mode Decomposition) and Monte Carol method. Then, the filtered EEG signals are analyzed by Hilbert-Huang Transform to obtain the corresponding Hilbert spectrum. Finally, useful information is extracted on the...
