摘要：In the OFDM SFN system that re-broadcasts signals received from the main station to a the relay station, the area where the delay of the received signal is longer than the guard interval length increases. This is in contrast to the SFN system that broadcasts signals simultaneously at both the main station and the relay station. This generates inter-symbol and inter-carrier interference, degrading the bit error rate. We developed a technique that allows the SFN system to re-broadcast signals received from the main station after adding an appropriate delay. In this paper, a receiver using an array antenna and a maximum ratio combining technique for this SFN system is proposed. Theoretical analyses and computer simulation show that this technique improves the bit error rate more than do conventional methods.
