| 摘 要： | 提出在素域上构造正则及近正则低密度校验码的一种新方法。采用这一方法构造的低密度校验码具有良好的结构。与被广泛研究的低密度校验码array codes as LDPC codes做了仿真比较，结果表明：此方法构造的低密度校验码采用迭代译码时具有优良的性能。

| Abstract: | A novel method to construct regular or near-regular Low-density parity-check codes from prime fields is proposed. The low-density parity-check codes constructed by the proposed method have a good structure. Compared the simulation results with those of the widely researched array codes as LDPC codes, it is shown that these Low-density parity-check codes perform well with iterative decoding. |
