Abstract :
An LDPC code structure using cyclic shift matrices and an efficient LDPC code construction algorithm using the characteristic matrix is proposed. It is shown that, with the proposed structure and construction algorithm, fast construction time, low encoding complexity and reduced memory without performance degradation can be achieved.
