代码说明:

说明:  二相相移键控(BPSK)是用二进制基带信号(0、1)对载波进行二相调制。BPSK是最简单的PSK形式,相移大小为 180°,又可称为2-PSK。在群点聚集的地方,其实都不是非常有关系,在该图像中,群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断,所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)

    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].
