Abstract (in Japanese) (See Japanese page) 
(in English) A SFN-GF (Single Frequency Network - Gap Filler) is expected to improve a reception quality of the digital terrestrial television broadcasting in area where it is difficult for radio waves to penetrate. It is important to analyze the channel characterization and specify the cause of multipath when the SFN-GF is established. In this paper, the received signals in the multi-channel are considered to improve the channel estimation precise. And also the phase variation in time domain into the transfer function are analyzed and compensated. As a result, the angles of multipath arrival power are shown in better estimation quality.
