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。
Based on the characteristics of meteor track, this paper proposes LDPC coding based on conditional matrix in meteor track communication (MBC) based on the analysis of LDPC coding and decoding algorithm, which can adapt to meteorological channel characteristics and improve system performance. Simulation results show that this LDPC code has better performance than RS codes and Mackay random LDPC codes.
