| 摘 要： | 针对非理想报告信道环境中的认知无线电多用户协同频谱感知问题，建立了协同感知三层模型；以单用户为例，分析了报告信道传输错误对单用户感知性能的影响；同时，基于Newman—Pearson准则推导了统计值传输和判决值传输条件下的最优协同频谱感知方法，并给出了平坦瑞利衰落环境下感知性能的上限。

| Abstract: | Considering the effect of non-ideal reporting channel on cooperative spectrum sensing in cognitive radio networks,a general 3-layer cooperative sensing model is formulated.The effect of reporting channel error to local sensing(summary statistics or decisions based) reliability is investigated.Optimal cooperative spectrum sensing schemes(in Newman-Pearson sense) that take non-ideal reporting channel into account are derived,which provide performance upper bound on cooperative sensing with reporting error.The... |
