摘要 提出一类非二元准循环低密度校验(QC-LDPC)码,其校验矩阵的列重为2.通过精心设计校验矩阵,使得对应的生成矩阵具有一些优良的性质:系统性;准循环;低密度.因此,可通过简单的移位寄存器电路实现低复杂度并行编码.仿真结果表明,提出的码和随机码的性能相当. This paper presents a class of nonbinary quasi-cyclic low density parity-check （QC-LDPC） codes, whose parity-check matrix consists of weighv-2 columns. The parity-check matrix is carefully designed such that the corresponding generator matrix has some nice properties： （1） systematic, （2） quasi-cyclic, and （3） low-density, which allow a parallel encoding with low-complexity through simple shift-register circuits. Simulation results show that the proposed codes do not have performance degradation compared with randomly constructed codes.
