| 摘 要： | 提出一种新的具有较大围长的正则LDPC码构造方法。首先介绍以矩阵分裂技术为基础的高围长正则LDPC码的构造方法，并在此基础上分析了设计围长时参数的选取方法。仿真表明，用这种方法构造的正则LDPC码围长可以达到12，并且在AWGN信道下的性能不差于相同参数、随机构造的LDPC码，在高信噪比时甚至优于相同参数的随机码。

| Abstract: | A construction method of strucred regular Low- Density Parity- Check（LDPC）code with large girth based on matrix dividing is proposed. The parameter option about girth accuting is analysed. Simulation results show that these codes＇ girth can achieve 12 based on this method,besides that,its performance is not worse than randomly constructed LDPC code in the same parameter under AWGN channel. Even better than the same parameter random code at high SNR situation. |
