摘要

中继协作传输能有效克服信道衰落影响，提高分集效果。为了提高全天候协作系统的频谱效率，在选择解码转发协议的前提下，研究了基于门限决策的中继选择策略，分析了其性能，并推导了高信噪比下的中断概率和频谱效率的近似表达式。仿真表明，在低信噪比和较少中继的场景中，不同门限下的中断概率十分接近，如果协作门限增加0.09，系统频谱效率可提高0.12；在高信噪比和较多中继的场景中，不同门限下的频谱效率较为接近，当系统中断概率为10<sup>-2</sup>时，如果协作门限减少0.9，可获得约1.1 dB的信噪比增益。

Abstract

Cooperative transmission can effectively overcome performance degradation caused by channel fading and thus improve diversity effect.In order to improve the spectral efficiency of all-time cooperative

relay selection strategy with selective decode-and-forward protocol based on threshold decision was mainly investigated.The performance was also analysed and the approximate expression of the outage probability and the spectrum efficiency with high signal-to-noise（SNR）were derived.Simulation results show that under low-SNR and few relays circulations

the outage probability under different thresholds are very close.If the collaboration threshold increases by 0.09

the spectral efficiency improves by 0.12.Under high-SNR and many relays circulations

the spectral efficiency under different thresholds are similar.When the system outage probability is 10<sup>-2</sup>

the collaboration threshold decreases by 0.9 and 1.1 dB SNR gain can be obtained.
