- Abstract
- Recently, Korea has made a plan to allocate CH 14-CH 51 (470 MHz-698 MHz) for DTV. Therefore, it is necessary to take into account compatibility and sharing between DTV and other potential service systems. This paper assumes that DTV operates on CH 51 (692 MHz- 698 MHz) and radio microphones operate on CH 52 (698 MHz-704 MHz) in spare band, and then analyzes compatibility between DTV and radio microphones. According to interference scenarios, protection requirements and system parameters, in the case of DTV potentially interferes with radio microphone, in the worst case, Minimum Coupling Loss (MCL) methods is used to determine that the required protection distance between DTV and radio microphone should be more than 1710.6 m for indoor scenario and 168.1 km for outdoor scenario; and Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT) is used to determine that the guard band between DTV and radio microphone is 2.4 MHz for indoor scenario and 2.9 MHz for outdoor scenario. The analysis results may offer a reference and be helpful for considering compatibility between DTV and radio microphones before DTV will be used. ©2009 IEEE.
