摘要

<FONT face=Verdana>针对流星余迹通信系统原理及信道特点，研究了基于自适应编码机制的流星余迹通信系统．根据流星余迹信道能量随时间呈指数变化的规律，在系统误比特率的约束条件下，通过实时估计出的流星信号接收信噪比，动态地改变系统TPC-RS编码的码率冗余，实现信息速率的自适应变化，有效提高了流星余迹信道的利用率．仿真结果和分析表明，在相同信道条件下，采用自适应编码较固定编码传输效率在误比特率为2×10^-4时可获得3.68dB系统增益，数据通过量提高了一倍，验证了该方案的有效性和可行性．

Abstract

According to the principle of meteor burst communication (MBC) and the characteristic of meteor channel

a mechanism for MBC based on adaptive coding transmission is proposed. On account of the system restriction of BER

the adaptive variable data rate transmission can be achieved by estimating the real-time signal-to-noise ratio and changing the coding rate of TPC-RS codes. Simulation results and analysis show that

the proposed adaptive coding tansmission system can obtain 3.68dB system gain when compared with that of the fixed coding transmission system with the BER of 2×10^-4 under the same channel conditions. And the experiment shows that the meteor channel can be fully utilized effectively.
