摘要

提出了一种构造短长度不规则非二元拟循环低密度奇偶校验码(QC-LDPC)的分环协集方法。该方法获得的QC-LDPC码在加性高斯白噪声(AWGN)迭代译码信道上具有较好的误码性能、错层和译码收敛性，译码复杂度较低。

Constructions of irregular nonbinary QC-LDPC codes: Cyclotomic coset approach

A cyclotomic coset approach for constructions of irregular nonbinary quasi-cyclic low-density parity-check (QC-LDPC) codes of short length is proposed. QC-LDPC codes obtained by this method perform reasonably well over the additive white Gaussian noise (AWGN) channel with iterative decoding in terms of bit-error performance, error-floor, and decoding convergence with low decoding complexity.
