Abstract (in Japanese) (See Japanese page) 
(in English) 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.
In this paper, an analyzing technique for the channel impulse response that is obtained from the pilot symbol from the received signal is proposed.
The amplitude and the delay time of a path is estimated to minimize the root square error between the replica signal and the channel obtained from the received signal.
In the proposed scheme, the hidden path by the larger path can be found and the impulse response can be re-contracted.
