Abstract: A method for encoding an LDPC(Low Density Parity Check) code by using a result of checking a predetermined parity is provided to effectively encode the LDPC code by slightly changing only a structure of an H matrix. A method for encoding an LDPC code by using a result of checking a predetermined parity includes the steps of: forming a parity bit check matrix with a dual diagonal structure based on an H matrix(901); calculating all parity bit by inserting an arbitrary binary number into a sub block unit(902); checking a parity bit corresponding to the sub block unit on the last position of the H matrix when the calculated parity bit is not right(903,904); searching a parity bit part where a result of checking the parity bit is represented as 1(905); performing an XOR operation of the parity bit part into which the arbitrary binary number is inserted and the parity bit part obtained through a simultaneous equation between the parity bits per the sub block unit(906); and determining, the parity bit satisfying a condition that a result of multiplying the H matrix by a code word vector encoded by the H matrix corresponds to 0, as the parity bit of the H matrix(907).
