摘　　要：流星余迹信道短时突发和时变的特点限制了系统的吞吐量,采用自适应调制技术可以使流星突发系统的吞吐量得到明显改善。文章针对自适应调制系统在流星突发信道上的吞吐量性能进行了分析,给出了系统吞吐量性能的推广公式及仿真结果,为流星突发系统中自适应调制的设计提供了理论依据。The throughput of meteor burst communication system is limited by the short-time and time-varied characteristic of the channel. Adaptive modulation technique can significantly increase the system throughput. In this paper, the.throughput performance of adaptive modulation for meteor burst channel was analyzed. An expression for the throughput performance was derived and the simulation result presented, which will he of use to the design of adaptive modulation scheme in meteor burst communication.
