Guangxin Yue · Beijing Youdian Xueyuan xuebao · 2011
In overlay sharing cognitive radio networks,an optimal scheme is proposed for improving cognitive system performance,it proves to minimize the outage probability on the premise of guarantee fixed detection performance.Analysis and simulation show that the optimal scheme can improve outage performance of cognitive system and enhance transmission reliability of cognitive network.
