基于之型分量码的系统非规则GLDPC码

摘要

首先提出了一种新型的编码结构——基于之型分量码的系统非规则GLDPC码；其次在加性高斯白噪声信道下利用基于高斯近似的密度进化理论设计ZS-IGLDPC码的度分布序列；最后对ZS- IGLDPC码进行了性能分析.仿真结果表明,中等码长的ZS- IGLDPC码在误码率性能方面有一定的优势.%A novel systematic and irregular generalized low-density code with zigzag component(ZS-IGLDPC) was proposed in this paper. The sequences of degree distribution was designed by Gaussian approximation based density evolution under the additive Gaussian white noisy channel. The performance of ZS-IGLDPC was analyzed by simulation. The simulation results show that the bit error rate of ZSrIGLDPC codes is less than other available codes for short and medium code length.
