Abstract
This paper describes the first study in Korea on the use of available TV white space (TVWS) channels that can be used in the South Sea for terrestrial digital television (DTV) broadcasting bands. Focusing on the Busan-Jeju route in the Soutn Sea of Korea, the possibility of using TVWS frequencies of DTV broadcast signals (channels 14-51 and 470∼698 MHz) was studied. Through the characteristic analysis of domestic DTV channels and other unusual measurement data, the DTV spillover signals of Japan are confirmed, and it is deduced that the available TVWS channels that could be used in the South Sea are affected. The analysis confirmed that channel No. 39 (623 MHz) can be used as an available channel for TVWS without interference from existing DTV channels in all seas between Busan Port and Jeju Port. Additionally, two channels, channel 45 (659 MHz) and 47 (671 MHz), were found to be available for the TVWS frequencies on the Busan-Jeju Island route section, excluding Busan Port and Jeju Port.
