Abstract: A method for designing an LDPC encoder using a fast back substitution operator is provided to improve an encoding speed using a separable double diagonal matrix. A matrix product and a modulo-2 operation are performed in a low parity check matrix comprised of a circulation matrix. The low parity check matrix is comprised using the separable double diagonal matrix in an encoding process of Richardson. The time of an inverse operation is reduced by the separable double diagonal matrix. The separable double diagonal matrix uses the circulation matrix as the component of the matrix. The back substitution operation is performed at high speed through a fully parallel or semi-parallel processing using the generalized inverse matrix shape about the separable diagonal matrix.
