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].

假定半波长间隔均匀分布线列布阵的阵元数N=16,若入射平面波为f=62.5Hz的正弦信号,信号持续时间为0.4s,
系统采样频率 =1 KHz,阵列加权为均匀加权,分别给出
a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时,指向90度的波束形成器的输出序列;
b)当平面波信号分别从0:1:180度方向入射时,指向90度的波束形成器的输出序列经过平方求和后的分贝数输出(把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives:
a) 90 degree response when incidence angles are: 0: 10: 100 degrees
b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )
