Abstract(in English)	In Digital Terrestrial Television Broadcasting(DTTB), it is necessary to analyze the propagation environment for improvement of the poor reception characteristics. In this paper, estimation of Direction of Arrival(DoA) and resolution of delay profiles are improved. In DoA estimation, the synchronization evaluation function is defined using estimated transfer functions. The symbol timing error is estimated to minimize the evaluation function. Accuracy of DoA estimation can be improved using proposed evaluation function. In the improvement of time resolution of delay profiles, it is effective that plural channels are connected and bandwidth is extended. In this scheme, the guard band is interpolated by the linear prediction filter based on RLS(Recursive Least Square) algorism. The proposed scheme can enhance the time resolution of the delay profile.
