摘要 为了在认知用户与数据融合中心之间的单跳直接式通信受阻时,通过邻居节点提供的中继辅助进行多跳通信,以完成数据融合中的感知结果报告,基于分层分簇的协作网络建模思想,提出一种多跳中继式协作模型,并在此基础上,使用Matlab GUI中的GUIDE工具,设计出一种用于中继式协作频谱感知环境的仿真平台。系统性能测试表明,所设计的仿真平台可对常见协作频谱感知算法,在多跳中继式模式下进行有效地仿真和性能分析。 A multi-hop relay model is proposed from the perspective of hierarchical-clustering col- laborative network. When the communication between cognitive users and data fusion center is blocked, this model can provide multi-hop connections via neighbor nodes' relay-assist to report sensing results reliably. Based on this, a relay cooperative spectrum sensing simulation platform (RecssSim) is designed using the GUIDE tool of Matlab GUI. System performance analysis shows that RecssSim can simulate typical cooperative spectrum sensing algorithms effectively in the environment of multi-hnn ro)~v onn tlnn
