Abstract: A hard-decision decoding method includes performing operations necessary for first updating of a check node while loading data, which is input to a decoder, to an input buffer; first updating the check node by using a result of the performing of the operations after storing data, corresponding to one codeword, to the input buffer; and performing low-density parity check (LDPC) decoding by using a result of the first updating of the check node.

Abstract translation: 硬判决解码方法包括：将输入到解码器的数据加载到输入缓冲器，执行第一更新校验节点所必需的操作; 首先通过使用存储对应于一个码字的数据之后的操作的结果更新所述校验节点到所述输入缓冲器; 以及通过使用校验节点的第一次更新的结果来执行低密度奇偶校验（LDPC）解码。
