| Abstract: | A schation scheme for reducing the intercarrier interference between the subcarriers of OFDM Terrestrial Digital TV Broadcast system based on differential modulation is proposed. The simulation shows that the differential moduleme can reduce the intercarrier interference effectively and needs little calculation time. It doesn't cause any reduction in bandwidth efficiency. So it is practicable |
| Keywords: | DTV OFDM intercarrier interference differential modulation |
