Abstract
Korea has made a plan to allocate CH 14~CH 51 (470 MHz~698 MHz) for DTV transition. Therefore, It is a necessary to take account compatibility between DTV service and other potential services. This paper assumes that DTV service operates on CH 51(692 MHz~698 MHz) and IMT service operates on CH 52(698 MHz~704 MHz), and then analyzes compatibility between DTV service and IMT service with Spectrum Engineering Advanced Monte Carlo Analysis Tool(SEAMCAT). The interference probability from IMT service to DTV service and capacity loss of IMT service due to interference from DTV service is studied, respectively. For the simulation, four interference cases in four different scenarios are considered. With considering the depolarization factor, a guard band of 8 MHz is required in the case of between IMT service downlink(DL) and DTV service, in the case of between IMT service uplink(UL) and DTV service, a guard band of 6 MHz is needed for the worst case of urban scenario on consideration of more then 15 dB increase of IMT system base station(BS) receiver blocking level.
