摘　　要：在研究流星余迹信道特性的基础上,结合2～64kb/s自适应变速技术与混合II型ARQ(IIHEC),提出了一种数据传输方法,并对数据帧结构设计、初始速率的选择、数据帧长的确定、变速准则等问题进行了分析,然后在自己设计的信道模型上进行了仿真,仿真结果表明这里提出的方法能够很好地改善平均数据通过量。This paper , on basis of the characteristic of the meteor-burst channel, joins the method of adaptive rate changing from 2kb/s to 64kb/s with hybrid II ARQ(IIHEC) to put forward a data transferring method. This paper also analyzes the questions of the frame architecture ,the selecting of the initial data rate and the frame length, and the rule of adaptive rate changing. The methods are simulated by computer based on the channel model designed by myself. The results show that the method presented in this paper can improve the average throughput greatly.
