基于SNR比较的协作感知用户选择问题的研究
Research of Partner Selection in Cooperative Spectrum Sensing Based on SNR Comparison
摘要
Abstract
In a practical circumstance, because the reliability of each cognitive user' s local sensing result is different, 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 cooperative spectrum sensing based on SNR comparison is proposed. Theoretic analysis and computer simulation show that the proposed scheme improves the detection performance and reduces the number of cognitive users which participate cooperative spectrum sensing at the same time, so this new scheme can improve the efficiency of cooperation.关键词
