Abstract: Proposed are an apparatus and a method for designing codes by using polar and algebraic codes. The operating method of the apparatus for designing a code may include a step of identifying a polar code defined as at least one information set, a step of identifying a parity matrix of the polar code, a step of identifying a vector corresponding to the polar code, a step of identifying a row that is representable in a way by linearly combining each row of the parity matrix, a step of identifying a specific binarization matrix in which the representable row does not exist, a step of generating a transformed parity matrix by adding the specific binarization matrix to the parity matrix and a step of generating a pre-code corresponding to the transformed parity matrix.
