Abstract:
Evoked potentials(EPs) are nonstationary and have characteristics that vary throughout stimulus trails. With the development of signal processing, new techniques focus on using fewer trails to extract the evoked potentials and to achieve single-trial extraction of evoked potentials finally. Therefore, fewer trials or single-trial estimation of evoked potentials has become the hotspot in the field of biomedical signal processing. In this article, signal processing methods of fast extraction of evoked potentials developed in recent years are reviewed and the approaches based on adaptive filter, wavelet transform, neural network and independent component analysis are discussed.
