中文摘要：

对频谱共享下采用放大转发传输策略的基本三节点协作分集系统链路选择问题进行研究。提出了一种分布式链路选择算法。理论分析了系统采用建议算法时中断概率上界和下界的表达式。研究结果表明，建议算法能获得与传统算法相近系统性能的同时，能有效地减少系统链路选择的反馈开销和时延。

英文摘要：

The issue of transmit link selection with amplify-and-forward scheme cooperative system in spectrum- sharing scenario is investigated. A distributed algorithm on transmit link selection is proposed, for which the corre- sponding system outage performance is analyzed and the upper and lower bounds are given. The results show that： the proposed distributed algorithm can achieve a similar feedback signaling overhead and the time slots are less performance to the centralized link selection algorithm; the than the centralized one.
