Abstract :
In this study, we measured terrestrial TV waves and FM waves from Korea to Japan to investigate overreach interference in digital TV waves. In order to evaluate co-channel interference in the TV waves, we proposed a measurement method that monitored both RSSI (Received Signal Strength Indicator) and CNR (Carrier to Noise power Ratio) of the digital TV waves and RSSI of FM broadcasting waves from several cities at the same time. Based on measurements of TV and FM waves, this study clarified that our proposed method was effective to evaluate the interference from Korea.
