Summary:
In this paper, an activation management method for cognitive radios is proposed to further alleviate interference with other radio systems. The idea is based on differences in radio frequency usage as human activities that weather, temperature, hours of a day, and days of a week effect on. Radio propagation simulation is carried out to estimate interference on the assumptions that cognitive radios operate at the same frequency of existing digital TV broadcasting. Result showed that coexistence of cognitive radios with TV broadcasting was possible in mountainous areas.
