| Abstract: | The opportunistic spectrum access(OSA) techniques in the ad hoc network are researched in this paper.An access scheme is proposed,which can not only suppress the interference between the secondary and the primary users,but also realize the fair and non-conflict resource sharing among secondary users.The solved problems include the spectrum sharing,and the optimal channel selection for secondary users which assure both the interference suppression and the self-optimization.For these purposes,the double selec... |
