| 摘 要： | 根据流星余迹信道的特点,在分析LDPC编译码算法的基础上,提出在流星余迹通信(MBC)中使用基于条件矩阵的LDPC编码,使其适应流星信道特点,提高系统性能。仿真结果表明,这种LDPC编码较RS码和Mackay随机构造的LDPC编码有更优的性能。

| Abstract: | Based on the characteristics of MBC(Meteor Burst Communicaiton) channel,and the analysis of the encoding and decoding algorithm of LDPC(Low Density Parity-Check),an LDPC coding algorithm based on conditional matrices was presented.This coding algorithm can improve the system performance by accommodating the characteristic of MBC channel.Simula-tion results show that the algorithm has better performance than RS codes and Mackay's codes. |
