摘　　要：协作通信作为一种新颖的无线通信技术,它的主要思想是通过中继节点参与协作传输,在目的端获得两个或者多个在空间上独立的信号样本,实现空间分集,获得分集增益。因此如何合理选择中继节点成为协作通信的关键问题之一。本文在协作通信模型及原理的基础上,对基于信道状态信息的中继选择算法进行了介绍,并对具体的选择算法的性能进行了仿真。As a novel wireless communication technology,the main idea of cooperative communication is to receive two or more independent signal samples in space at the destination so as to achieve spatial diversity and diversity gain via the relay nodes participate in the cooperative transmission.Consequently,how to selection a suitable relay node become one of the key issues in cooperative communication.The relay selection algorithm based on channel state information has been presented on the system model and principle of the cooperative communication.Finally,the numerical simulations for the specific algorithms are provided to verify the correctness of the analysis.
