A new method for analysis of electroencephalogram (EEG) signals using empirical mode decomposition (EMD) and Fourier‐Bessel (FB) expansion has been presented in this paper. The EMD decomposes an EEG signal into a finite set of band‐limited signals termed intrinsic mode functions (IMFs). The mean frequency (MF) for each IMF has been computed using FB expansion. The MF measure of the IMFs has been used as a feature in order to identify the difference between ictal and seizure‐free intracranial EEG signals. It has been shown that the MF feature of the IMFs has provided statistically significant difference between ictal and seizure‐free EEG signals. Simulation results are included to illustrate the effectiveness of the proposed method.
