摘要:
在实际情况的认知无线电环境下,由于认知用户的感知可靠性存在差异,并不是参与协作的认知用户越多,感知性能越好.综合考虑协作的必要性与协作的增益两方面因素,提出了一种基于信噪比(SNR)比较的协作感知用户选择方案.理论分析及仿真结果一致表明:该方法在有效地提高频谱感知检测性能的同时,减小了参与协作感知的用户数目,提高了协作效率.
Abstract:
In a practical circumstance,because the reliability of each cognitive user’s local sensing result isdifferent, the detection performance cannot be improved with the increase of the number of participating users.In consideration of the necessity of cooperation and collaboration gain, a new scheme-partner selection in coop-erative spectrum sensing based on SNR comparison is proposed. Theoretic analysis and computer simulationshow that the proposed scheme improves the detection performance and reduces the number of cognitive userswhich participate cooperative spectrum sensing at the same time,so this new scheme can improve the efficien-cy of cooperation.
