10-3 地上無線回線による双方向型放送の基礎検討 : OFDMによるリターンリンクの検討

抄録

Digital TV broadcasting and interactive broadcasting have been studied for new TV services. In this paper, return link by OFDM (Orthogonal Frequency Divisio Multiplex) using terrestrial radio wave is proposed, and theoretical studies of BER (Bit Error Rate) degradation caused by frequency offset and symbol timing error are described.
