Construct the short length of QC LDPC codes without girth 4 and girth 6(The Program to construct the short length of QC LDPC codes without girth 4 and girth 6 Copyright (C) Yang XIAO, Jun FAN, BJTU, July 26, 2007, E-Mail: yxiao@bjtu.edu.cn. This program presents an approach [1] for constructing the short length of LDPC codes with girth 8. First, we design 3 submatrices with different shifting functions given by our schemes, then combine them into a matrix according to our approach, finally, expand the matrix into a desired parity-check matrix using identity matrices and cyclic shift matrices of the identity matrices. The simulation results in AWGN channels show that the codes which can be obtained by the generator matrix derived from this check matrix for encoding the random information bits are as good as random LDPC codes [1].
