摘要

针对认知无线电网络中次用户（SU）参与频谱感知的积极性低以及SU到融合中心（FC）的信道条件差

造成发送到FC的数据不可信的问题

提出一种基于反拍卖技术（RAT）的中继协作频谱感知算法。该算法将SU分为普通次用户和中继次用户

在这两种SU之间采用RAT的方式激励SU参与到频谱感知当中

以解决SU的积极性低的问题

通过中继的方式可以解决信道条件差的问题。仿真结果表明

所提方法的感知性能明显好于非中继方法

并且提高了用户的积极性。

Abstract

In cognitive ratio networks

the enthusiasm of Secondary Users’（SU）participation in spectrum sensing is low and the untrusted data is sent from SU to the Fusion Center（FC）due to the poor channel condition.Considering these problems

a cooperative spectrum sensing algorithm based on Reverse Auction Technology（RAT）-Reverse Auction is proposed in this paper.This article refers to the incentive mechanism of RAT.The user is divided into ordinary secondary users and relay secondary users.The use of RAT between these two secondary users encourages the secondary users to participate in the spectrum perception to solve the problem of the lower initiative of SU

and the problem of channel condition difference can be solved by means of relay.The simulation results show that the sensitivity of the proposed method is better than the non-relay method

and the user’s enthusiasm is improved.
