摘要 基于行列约束条件提出适用于光通信系统中一种新颖的高码率与码长的QCLDPC码构造方法。该方法可在取得较好纠错性能的同时降低编码复杂度。并利用该方法构造出一种适用于光通信系统的非规则QC-LDPC(3591,3351)码。仿真分析表明:在BER为10-7时,该QC-LDPC(3591,3351)码的净编码增益分别比ITU-T G.975中RS(255,239)码和ITU-T G.975.1中LDPC(32640,30592)码提高2.13d B和1.32d B;且比用SCG方法构造的LDPC(3969,3720)码和利用有限域乘群方法构造的规则QCLDPC(5334,4955)码提高0.66d B和0.40d B,因而该QC-LDPC码新颖构造方法的纠错性能优越并在光通信系统中具有较好的应用前景。
