摘　　要：针对多用户的TDMA无线自组织协同通信网络,深入研究了基于有限信息反馈的最佳编码协作中继选择策略,在瑞利和莱斯信道条件下对该协议的中断概率和误码率性能进行了计算机仿真,并对协议做了进一步细化和优化。仿真和分析结果表明,该中继选择策略的中断概率和误比特率性能较传统策略有较大提升,且改进后的方案能明显减少协同交互信息开销。In this paper,it considers a TDMA wireless ad-hoc coded cooperative system where all the nodes only have one antenna,and a best-relay selection scheme with limited feedback is studied.Simulation results over flat Rayleigh and Rice slow fading channels show that the scheme has good outage probability and bit error probability in which it outperforms other conventional schemes.Then,an improved detailed executable scheme is provided.Finally,communication overhead assessment is given based on the two strategies,which indicates that the improved strategy costs fewer bits to communicate with other nodes compared with the original.
