- In this paper, we proposed the method for calculating the Protection Ratio (PR) of the Advanced Television Systems Committee (ATSC) broadcasting system from the Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) broadcasting system through the computational experiment. For this, the transmitter/receiver of the ATSC system and transmitter of the ISDB-T system were modeled. By integrating those, the computational simulator for setting up the PR of the ATSC system from the ISDB-T system was implemented. The ATSC TV signal was regarded as the desired one and the ISDB-T TV signal was regarded as the interfering one. In order to simplify the simulation complexity, it was modeled sending/receiving signals in the Intermediate Frequency (IF) band instead of those in the RF band. And it was assumed that one received signal was considered in the channel modeling and there's no Additive White Gaussian Noise (AWGN). By using the calculated PR value, the coverage prediction considering the interference was performed between the adjacent nations which use the different digital broadcasting system. ©2007 IEEE.
