在本文中，我们研究了非内存二进制输入输出对称（MBIOS）通道传输的非二进制低密度奇偶校验检查（LDPC）的误差地板。我们阐明了BP解码器在MBIOS通道上成功解码曲折周期代码的必要条件。我们使用上述条件来消除非二进制LDPC代码集合，以分析并降低误差地板。最后，我们显示了MBIOS通道上消除的LDPC代码集合的误差地板的上限和下限。
In this paper, we investigate the error floors of non-binary low-density parity-check (LDPC) codes transmitted over the memoryless binary-input output-symmetric (MBIOS) channels. We clarify a necessary and sufficient condition for successful decoding of zigzag cycle codes over the MBIOS channel by the BP decoder. We expurgate non-binary LDPC code ensemble to analyze and to lower the error floor by using the above condition. Finally, we show upper and lower bounds of the error floors of the expurgated LDPC code ensemble over the MBIOS channel.
