| Abstract(in English) | Cognitive radio should have the sensing technology. In this paper, we proposed a cooperative sensing system that radio stations cooperate to accurately sense the existence of radio waves. In the proposed system, the radio station which wants to know the presence or absence of radio waves and the neighbor radio stations observe the received power. The recieved power observed at the neighbor radio station is multiplied by weight which is proportional to the distance between radio stations. The powers are added, and then the presesnce or absence of radio waves is judged by comparing the added power to threshold. Simulation results show the proposed system is superior to conventional systems in false alarm rate under required misdetection rate. |
