在这项工作中，我们研究了解码转发协作网络中的闭环扩展正交空时分组码，并提出了一种具有中继选择的可更新自动重复请求协议。该系统将正确解码的中继纳入一个中继集中，根据信道信息选择该中继集中的最佳中继，并借助自动重传请求消息中的反馈，采用扩展正交空时分组码方案。通过考虑继电器的选择，可以提高系统性能。仿真和分析结果证明了该方案的有效性，取得了比传统中继方案更好的性能。版权所有 © 2012 约翰·威利父子有限公司
In this work, we investigate the closed loop extended orthogonal‐space time block codes in decode‐ and‐forward cooperative networks and propose an updatable automatic repeat request protocol with relay selection. In the system, the relays decoding correctly are incorporated into a relay set, the optimal relays within this relay set can be selected based on the channel information, and the extended orthogonal‐space time block codes scheme is employed with the help of the feedback in automatic repeat request message. With the consideration of the relay selection, the system performance can be improved. Simulation and analysis results prove the efficiency of the proposed scheme, which achieves better performance than conventional relay schemes. Copyright © 2012 John Wiley & Sons, Ltd.
