| Outline of Final Research Achievements |
The cognitive radio system has been promising as a formula because the scarcity of the wireless resources are forcing all wireless users. In our study, we propose a method for discriminating between a radio wave which is used for communication and a microwave which is used for object except communication by employing an amplitude probability distribution (APD). The proposed method can find a useful wireless resources which is not used in conventional cognitive radio system. In measurement experiments, the received power is measured in the cases of the wireless LAN and microwave oven, respectively. Then, we confirm that the system can be discriminated by using the APD which is derived from easy calculation.
