| 摘 要： | 提出了一种基于目标对象的最佳中继协作频谱感知方案(Pe-BRCS),通过最小化报告信道上的错误传输概率为目标选择最佳中继,以提高感知性能;为了降低计算复杂度,进一步提出了简化的最佳中继,协作频谱感知方案(simplified_BRCS)。仿真结果表明:相比传统SINR-BRCS方案,Pe_BRCS方案有效降低了报告信道上的错误传输概率,可以在增加较少计算复杂度的条件下提高感知性能;simplified_BRCS方案可以在不增加复杂度的情况下很好地近似Pe_BRCS方案。

| Abstract: | Target based Cooperative Spectrum Sensing(CSS) scheme with best relay(Pe-BRCS) was proposed.In this scheme the best relay was selected by minimizing the reporting error probability to improve the sensing performance.Furthermore,to reduce the computational complexity,a simplified CSS scheme with best relay(simplified-BRCS) was proposed.Results of numerical simulation show that,comparing with traditional SINR-BRCS,the reduced reporting error probability can be achieved effectively by the proposed Pe-BRCS with little computational complexity.The performance obtained by the simplified-BRCS scheme is similar to that of Pe-BRCS but without increase in computational complexity. |
