| 摘 要： | 文章提出一种新的合作感知方法,实现网络中一个认知用户与多个中继用户的合作。认知用户通过能量检测选择中继用户,根据可信度对中继用户进行筛选,采用＂大多数＂准则对感知结果进行融合。仿真结果表明,与独立检测和传统的合作检测相比较,该方法具有更高的检测性能与频谱利用率。

| Abstract: | A new cooperative spectrum sensing technique based on relay-transmission for cognitive radio is proposed.This method can achieve cooperation between one user and multi-user in network.Firstly,cognitive users choose its relay-users by energy detecting.Secondly,according to the reputation,relay-users are selected.Finally,the sensing information are combined with ＂Majority＂ theory.Simulation results show that this method can increase the detection probability of the CR and have better spectrum utilization ratio. |
