摘要 指出了在卫星回传系统中采用Turbo码和LDPC码作为纠错码的优缺点,介绍了LDPC码的常用构造方法。在此基础上提出了一类适于在卫星回传系统中使用的LDPC码的构造方法,最后对使用该方法构造的LDPC码在纠错性能上,和Turbo码进行了仿真分析比较。 Firstly, this paper points out the disadvantage and advantage of Turbo Codes and LDPC codes which are used in satellite interactive communication system, then it introduces the common construction method. Subsequently, this paper putts forward a new construction method of a type of LDPC codes which is fit for satellite interactive communication system. Finally, error correction performance of LDPC Codes which are constructed using this method and Turbo codes were simulated comparison.
