| 摘 要： | 流星突发通信是一种利用流星余迹进行通信的短时、突发通信方式。如何在较短通信时间内尽可能多的实现数据的可靠传输,始终是研究者关注的问题。传统的固定速率编码方案无法很好地适应信道变化,因此提出变速率编码以提高系统性能。通过对两种方案研究,对变速率编码算法进行了改进。仿真结果表明,改进后的变速率编码方案可明显改善系统性能。

| Abstract: | The meteor burst communication（MBC） is a means of paroxysmal radio communication by meteor trail.It is always considered by researchers to achieve reliable data transmission in such a short trail duration.The conventional fixed-rate coding scheme can′t adapt to the time-varing channel,so the variable-rate coding scheme is proposed.The variable-rate coding algorithm is improved by studing both of the schemes.The simulations show that the improved scheme can greatly improve the performance of MBC system. |
