An Iterative Wiener Filter Method for the Restoration of Auditory-evoked Potentials with High Rate Stimulation
Lin Lin · Journal of Biomedical Engineering Research · 2008
To restore the high order transient response generated from the overlapping process due to high rate paradigm.Using Wiener filter approach developed previously and the mathematical model of high order response,we thus proposed a supplementary method to carry out the power spectrum estimation of the response using an long-term memory iterative strategy without the need of a prior knowledge on the transient response itself.Validity is accomplished on the simulated data as well as the real AEP data,which yields the performance close to the ideal and theoretical solution.
