Estimation of Arrival Time by Using Multi-Channel in Digital Terrestrial Television

Abstract

An improvement scheme for degradation of reception characteristics of the digital terrestrial television broadcasting (DTTB) is an important issue. The degradation is caused by multipath effects and masking problem of the direct path, thus an analyzing technique for the channel is significant. Resolution of distance in delay profile is not enough using only one channel. In this paper, the multi-channel connection scheme is proposed. Resolution of distance in delay profile is improved by the proposed scheme.
