产生固定周期数的正弦脉冲信号 使用该函数时必须预先设定如下参数：正弦波的频率Fp，构成输出脉冲的正弦波的周期个数Nc，脉冲幅度A每个周期的采样点数smp。函数有两个输出：脉冲波形，以响亮sinpulse的形式输出，采样周期dt。(Produce a fixed number of cycles of the sine pulse signal         Use this function must be pre-set the following parameters: a sine wave of frequency Fp, constituting the output of the pulse cycle of the sine wave of the number Nc, the sampling points for each cycle of the pulse amplitude A smp. The function has two outputs: output pulse waveform, the a loud sinpulse form, the sampling period dt.)

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].
