Guangtongxin yanjiu, 2012 为提高100Gbit/s光通信系统的传输距离,构造了高增益的NB-QC-LDPC（非二进制准循环低密度校验码）,这种纠错码构建在伽罗华域上,适合于采用QPSK（正交相移键控）或DQPSK（差分正交相移键控）调制格式的100Gbit/s系统。文章采用对数傅里叶和积译码算法分析了NB-QC-LDPC的误码性能。结果表明,与二进制准循环低密度校验码相比,码长为500、码率为0.8的NB-QC-LDPC,在误码率为10-8时可提供约1dB的编码增益。同样,在误码率为10-8时,若码率从0.9降低至0.8,NB ...

The Performance Simulation of MIMO-OFDM System Based on QC-LDPC [PDF]
, 2007 QC-LDPC码是一个十分重要的LDPC码研究分支。QC-LDPC码(准循环低密度奇偶校验码)是一类结构化的LDPC码,其校验矩阵H采用准循环方式构造,具有实现复杂度低的特点,易于硬件实现。大量研究人员认为,MIMO-OFDM技术将会成为4G的核心技术。将QC-LDPC码与MIMO-OFDM系统相结合,分析了在时变频率选择性衰落信道下的系统性能。仿真结果表明,在时变频率选择性衰弱信道下,QC-LDPC码与随机构造的LDPC码具有接近的系统性能。Quasi Cyclic Low Density ...
