Measurement of isolation between receiving and transmitting antenna for the same frequency in a relay television broadcasting. : The possibility of SFN

Abstract

One of the problem in achieving SFN television broadcasting with OFDM method is the isolation between relay stations. In this paper, we verify the actual measurement data that is got from current analog frequency relay facility. As a result we come to the conclusion that these are some difficulties in obtaining coupling with current facilities. To achieve SFN, it is necessary to utilize landform or other factors.
