摘　　要：在增量中继传输策略基础上,提出了基于ARQ协议的协作分集传输技术,推导了三节点模型在平坦瑞利慢衰落信道下BPSK调制的平均误码率性能、信道利用率以及分集增益。仿真结果表明,与传统ARQ和增量中继传输相比,文章提出的协作分集技术有更好的误码率性能,并且达到了满分集增益。Based on Incremental relaying protocols,a cooperative diversity transmission technology with ARQ protocol was proposed.BER,channel efficiency and diversity order were analyzed over flat slow Rayleigh fading channel with BPSK modulation.Simulation results show that the proposed technology has better BER performance compared with the incremental relaying and traditional ARQ protocol,and can achieve full diversity order.
