ADAPTIVE OPTIMUM WAVELET FUNCTION SELECTED METHOD AND SYSTEM

摘要

PURPOSE: An optimum wavelet function selecting method and a system thereof are provided to subdivide entire time section into dynamic segments and to efficiently perform various signal process by applying an optimum wavelet function according to the subdivided dynamic segments. CONSTITUTION: A section subdividing unit(110) subdivides the entire time section about input signals into dynamic segments. A coefficient calculating unit(120) applies the subdivided dynamic segments to a mother wavelet function. The coefficient calculating unit calculates a cross-correlation coefficient through input signals. A table generating unit(130) generates an n-gram table through the calculated coefficient.
