地上ディジタルテレビジョン放送における単一周波数ネットワークの検討

抄録

OFDM (Orthogonal Frequency Division Multiplexing) is a useful digital modulation method for DTTB (Digital Terrestrial Television Broadcasting) systems and superior to the multi-path environment. SFN (Single Frequncy Network) using OFDM has been studied for DTTB network in order to improve frequency utilization efficiency. In this paper, service area is estimated when SFN is applied to real broadcasting environment in Japan.
