Abstract
According to convert from analogue TV signal to Digital TV signal on 31 December 2012, research on utilization of TV white space (TVWS) has been being actively proceed. It is expected that various low power devices use the TVWS, so interference between DTV relay system and low power devices using in TVWS can be occurred. Therefore, in this paper, we analyzed the interference between DTV relay system and low power devices. So, we calculated a minimum coupling loss (MCL) and compare the resulting value with a path loss for determining whether there exists a potential interference or not. The minimum separation distance is determined when the path loss is larger than the MCL. In the simulation results, we setup the victim and interferer system as DTV relay system and low power devices, respectively.
