一种新的编码协作中继选择策略性能仿真

Incremental-Best-Relay Selection Scheme in Coded Cooperative Networks

针对多用户的编码协作通信网络,给出了增量中继和机会中继结合起来的增量最佳编码协作中继选择策略并对其进行了计算机仿真。结果表明,与其它编码协作节点选择方法相比,该策略在取得机会中继中断概率性能的基础上,进一步节省了信道资源,提高了系统有效信息速率。

For the multi-nodes coded cooperation network,a novel cooperative transmission scheme,the Incremental-Best-Relay selection scheme in coded cooperative networks,is studied which employs incremental relaying strategy in the opportunistic relaying strategy.Simulation results show that the proposed scheme can achieve the same outage probability as opportunistic relaying strategy and higher effective rate while saving much system resources.
