摘要
协作分集是近几年无线通信技术的研究热点。在协作通信中合理地选择中继能给系统带来更大的增益。本文介绍了协作时机的选择和协作关系的形成,重点讨论了3种主要的中继选择方法:基于位置信息、基于平均接收信噪比和基于瞬时信道状态的中继选择算法,并对这些方法进行了分析和比较。
In recent years there has been an increasing focus on the cooperative diversity in wireless communications, the reasonable selection of the relay in cooperative communications can give high-gain. In this paper, we introduce the choose of cooperative timing and the form of cooperative relation, focused on three main methods of relay selection： location-based information, based on the average received signal to noise ratio and based on the instantaneous state channel relay selection algorithm, and then give an analysis and comparison to these methods.
