Abstract

Based on the property of bandlimited wavelet

a matching method is developed for constructing a new bandlimited scaling function

which has the similar frequency spectrum as the original signal in the band occurring main energy.The scaling filter is an optimizing filter

which locks the frequency band in that energy is concentrated

so that the filter output of the interested frequency components increases.The original signal can be processed with optimize wavelet in real time.The experimental results with electroencephalogram signals demonstrate the method is effective.
