    • There is provided to a method for encoding an LDPC (Low Density Parity Check) code using the result of checking a previously specified parity, including the steps of: forming a parity bit check matrix having a dual diagonal structure consisting of (N-K) rows for check nodes and (N-K) columns on the basis of the H matrix; calculating the values of all the parity bits by inserting a given binary value in sub-blocks, with the parity bit check matrix formed on the H matrix; if the values of the parity bits are incorrect, checking the parity bit corresponding to the sub-block located in the last part of the H matrix; searching the parity bit parts where the parity bit check result is represented as “1”; performing an XOR operation in sub-blocks on the parity bit part obtained through a simultaneous equation between the parity bits of the searched parity bit parts and the parity bit parts; and determining the value of the parity bit satisfying the condition that the value obtained by multiplying the H matrix by a code word vector.
    • 提供了一种使用检查先前指定的奇偶校验的结果来编码LDPC(低密度奇偶校验)码的方法,包括以下步骤:形成具有由(NK)行组成的双对角线结构的奇偶校验位校验矩阵,用于 基于H矩阵检查节点和(NK)列; 通过在H块中形成奇偶校验位校验矩阵,在子块中插入给定的二进制值来计算所有奇偶校验位的值; 如果奇偶校验位的值不正确,则检查与位于H矩阵的最后部分中的子块相对应的奇偶校验位; 搜索奇偶校验位检查结果表示为1的校验位部分; 在通过搜索到的奇偶校验位部分的奇偶校验位与奇偶校验位部分之间的联立方程获得的奇偶校验位部分的子块中执行异或运算; 以及确定所述奇偶校验位的值满足将所述H矩阵乘以码字矢量而获得的值的条件。
