摘　　要：文中给出了一种基于节点选择的Turbo编码协同ARQ(TC-ARQ)协议方案,并从理论上证明了采用基于节点选择的TC-ARQ协议相比传统的Turbo ARQ协议(T-ARQ)能获得更高的分集增益以及比非节点选择的协同ARQ协议更低的误帧率。仿真结果证实了该方案相对T-ARQ的优异性能,并仿真分析了节点数对节点选择性能增益的影响。This paper gives an ARQ protocol with cooperative turbo coding based on node selection. It is proved that the proposed scheme can obtain higher diversity gain than the traditional ARQ protocol with turbo coding （T-ARQ）, and lower FER （Frame Error Rate） is obtained compared with cooperative ARQ protocol without node selection. Simulation results show that the proposed scheme can provide higher performance than T-ARQ. The effects on performance gains brought by changing the number of nodes in node selection are also simulated and analyzed.
