Some important issues remain to be better resolved before sensing technologies can be widely used in applications. For the reason, spectrum sensing is not selected as the mandatory solution for protection of primary users in current FCC regulations on usage of TV white space (TVWS). In this work, we introduce a sensing prototype for detection of Japanese digital TV signals. The prototype targets at...
Considerable efforts have been made by research entities in the world to develop sensing prototypes for digital TV (DTV) signals that can fulfill the FCC sensing requirement. FCC official test results for some sensing prototypes have shown that adjacent channel interference (ACI), which truly exists in real sensing world for DTV signals, has significantly increased the difficulty of fulfilling the...
