摘　　要：针对车载动中通阴影信道中系统通信存在的问题与不足,根据动中通信道特点,分析动中通信道中传输效率偏低的原因,提出了基于突发通信的自适应控制算法。根据对阴影信道的分析,得出原有传输方法适用性差的结论。通过引入发送帧数自适应算法,改善了阴影信道的高丢包率,提高了通信效率。实验结果说明:自适应的阴影信道突发控制能够有效降低丢包率,提高信道通信效率。In view of the existing problems and shortcomings of system communication in the shadow channelof vehicle-mounted Sat-com on the move（ SOTM） ,based on the characteristics of SOTM channel,the reason for low transmission efficiency in the channel is analyzed,and an algorithm of self-adaptive control based on burst communication is put forward. According to the analysis of shadow channel,it is concluded that the original transmission method is of poor adaptability. By introducing a frame-number self-adaptive algorithm,the high pocket loss rate of shadow channel is decreased,and the communication efficiency is increased. The experimental results show that self-adaptive burst control for shadow channel is able to effectively decrease the pocket loss rate and improve the efficiency of channel communication.
