摘　　要：在流星突发通信中,混合ARQ技术能有效保障数据传输的有效性和可靠性。文中通过对传统的增量冗余传输方案进行分析,提出了一种改进的短码字重传冗余HARQ方案,并对单条余迹下两个站点间的数据通信进行了仿真。理论分析和仿真结果表明,改进后的方案能有效抑制噪声干扰,增加吞吐量。Hybrid ARQ can guarantee the efficiency and reliability of data transmission in meteor burst communication（MBC）.An improved scheme is proposed in this article by analyzing conventional incremental-redundancy block transmission,and some simulations have been done for communications between two sites during a trail.The theory analysis and simulations show the improved scheme can effectively control noise interference and enhance the throughput.
