Abstract:
Event-related potentials (ERP) is pertinent to medical research and clinical diagnosis. Estimation of single event-related potentials (sERP) is the objective of ERP processing. A new technique, adaptive moving averaging ba sed method for estimation of sERP, is presented. After analysis of the properties of background noise by crossingzero, the window length of moving averaging is adapt ively set according to the maximum width of the impulse noise for each recorded raw data. The experiments are made with real recorded data and the results demon strate that the performance of sERP estimation is excellent. So the method propo sed is suitable to sERP processing.
