Coezistence between Cognitive Radio Network and Digital TV
In order to study the coexistence between cognitive radio network and incumbent services, two representative systems of WRAN and DTV were selected. A simple interference analysis method was proposed through a coexistence scenario. Through calculation and simulation, a series of critical values were found. 8km and 20km of WRAN cell radius are of great significance to control the interference to DTV. If WRAN cell radius less than 8km, more than one tier of interferers are permitted. On the other hand, when WRAN cell radius exceeds 20km, the distance from DTV receiver to WRAN BS should be larger than the sum of the two radiuses (R+r).
