LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 (LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.

说明：  利用MATLAB进行数据拟合，常见的数据拟合方法。包括：一元函数插值、样条插值、多项式插值或拟合 、曲线拟合、拉格朗日插值法等。(MATLAB data fitting, common data fitting methods. It includes: interpolation of unitary function, spline interpolation, polynomial interpolation or fitting, curve fitting, Lagrange interpolation, etc.)

说明：  应用MATLAB的M文件编程方法过行信号频域分析。分别用矩阵运算的方法计算方波的DFS，在60的时窗宽度上方波宽度分别为5与12。并且画出x(n)和DFS(x(n))的杆状图。(Application of MATLAB M-file programming off-line signal frequency domain analysis. Were calculated using matrix calculation of square wave of DFS, in the 60' s when the window width the width of the top of wave 5 and 12, respectively. And draw the x (n) and DFS (x (n)) of the rod-shaped graph.)
