| 摘 要： | 高可靠性的频谱感知是认知无线电实现的基础.在认知无线电网络环境下,提出了一种可靠的合作频谱感知方案.认知网络中的独立节点分别计算频谱感知结果的可信任程度,融合中心预分选各节点的感知结果,剔除终端的错误感知数据,利用D-S证据融合方法得到最终感知结果.该方式能够克服阴影效应、衰落信道以及自私设备所造成的感知信息失真问题....

| Abstract: | Reliable spectrum sensing is the foundation of cognitive radio networks.Due to the effects of channel fading and shadowing,individual CRs may not be able to reliably detect the existence of a primary radio,who is a licensed user for the particular band.In cognitive radio network,a useful cooperation scheme for spectrum sensing based on D-S evidence theory and pre-selecting approach is introduced.Individual sensing node calculate credibility based on sensing results,and then,data from all individual nodes ar... |
