Abstract
A novel method for constructing the Latin square Low Density Lattice Codes (LDLC) parity check matrix is proposed in this paper. Based on the permutation matrix, a 6-cycle matrix is build firstly. Then the elements involved in the 6-cycle are detected and swapped, which is on the basis of the theory of adjacency matrix. Therefore, we obtain a check matrix, which is 6-cycle free and the nonzero elements obeying random distribution. Simulation results demonstrate that the proposed method has a lower symbol error rate (SER) compared with the previous works.
