Abstract
Recently, the digital television transition from analog television to digital television has been progressing in terrestrial broadcasting. As a result of the DTV transition, additional reassignments and deployments of TV White spaces (TVWS) caused by co-channel interference (CCI) were needed. In this paper, we investigate the TVWS caused by CCI using Longley-Rice and ITU-R P.1546 propagation model, which are the most widely-used propagation model. In addition, we analyze the service coverage radius and CCI radius according to the height of transmitter antenna and transmitting power. The results show that the ratios of CCI radius to service coverage radius in Longley-Rice and ITU-R P.1546 propagation model are about 2.54 and 2.07, respectively.
