In Digital Terrestrial Television Broadcasting (DTTB), delay profile is measured from Scattered Pilot signals. But, direct current component remains behind in delay profile by attered Pilot signals including desired wave component. Therefore it is difficult to measure an existing multi-path component near a desired wave. This paper propose the method to reduce the direct current component from Delay profile. Delay profile calculated by Proposed Method can measure an existing multi-path near a desired wave.
