| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, a frequency sharing system as a form of cognitive radio is investigated.Reliable detection of other radio systems is crucial for this system in order not to interfere with other systems excessively.In wireless communication channels, there is uncertainty in the received signal level due to multipath fading and shadowing. Cooperative sensing techniques in which radio stations share their sensing information can improve the detection probability of other systems. However, sensing information reported by several sensing stations may increase the false detection probability. A combination of cooperative sensing and transmit power control based on sensing information collected by using multi-hop transmission from all sensing station can reduce the false detection probability while maintaining the outage probability of other systems. In this paper, the performance of this system is evaluated in spatially correlated shadowing and Rayleigh fading environment. |
