Flexible construction of girth-six QC-LDPC Codes(The program constructs girth-six QC-LDPC codes given row-weight,k, column-weight,j, and sub-matrix size,m. The obtained parity-check matrix is stored in H. The construction has flexibility in that j,k and m can be varied.The program achieves girth-six by applying the row-column constraint. There are m rows in j submatrices. No two rows should share the same column more than once. This constraint is applied to avoid 4-cycles. The construction has flexibility in that j,k and m can be varied.)

matlab摄像机标定工具箱，国外的，可以通过这个工具箱作2D靶标定摄像机(Matlab toolbox camera calibration and abroad, through the toolkit for 2D camera calibration target)

程序对2发2收系统进行SVD算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端采用最大似然检测算法，仿真其误比特率特性。(The SVD algorithm simulation program 2 admission system. Send signals using QPSK modulation, channel prevail static Rayleigh flat fading channels, the introduction of noise with mean 0 Gaussian white noise, the receiving end using the maximum likelihood detection algorithm, simulation of the bit error rate characteristics.)

这个函数，很重要，不是用不行，这是一个泊松分布，是一个一维的，长度是1000的分布，还可以自己添加plot绘图函数，查看泊松分布。(This function is very important, do not use this function, very important, not with no, this is a poisson distribution is a one-dimensional, length is 1000 distribution, still can add your own plot drawing function, check poisson distribution. No, use your Linux will be very smooth.)

使用MATLAB编写的入门实例，这是一款很简单易懂的程序，欢迎大家看看(Getting Started with examples written in MATLAB, which is a very straightforward procedure, please take a look)

用MATLAB实现对图像的去噪，可以通过修改里面的参数达到不同的效果，调用的是MATLAB的小波包实现的。(Using MATLAB to realize the image denoising can be achieved by modifying the parameters inside the different effects, call the MATLAB wavelet packet implementation.)

说明：  这个主要是当前IT流行的C和C++开发的资料。这里稍作整理，(The IT major is currently the popular C and C++ development information. Here a brief order,)

说明：  好几个关于随机振动，结构动力学方面求解的算法，包括PSD法，PEM法，模态空间法，虚拟激励法等算法的基础程序(Several algorithms for solving random vibration and structural dynamics, including PSD method, PEM method, modal space method and virtual excitation method, are introduced.)

说明：  根升余弦函数，主要用在调制时的成型时使用(Root raised cosine function, mainly used in modulation used at the time of molding)

矩阵数值分析的matlab编程,包括插值与拟合等问题(Matrix numerical analysis matlab programming, including issues such as interpolation and fitting)
