Abstract
In Digital Terrestrial Television Broadcasting (DTTB), the identification of multipath is important to improve its reception quality. In order to enhance the resolution of the delay profile, it is effective that plural channels are connected and the frequency bandwidth is extended. However, the guard band is existed between each channel and the frequency response is dropped off. In this report, interpolation scheme by using the adaptive filter based on the RLS algorism is proposed to enhance the resolution of the delay profile.
