通过学习LDPC编译码原理，编写了LDPC码的编译码程序。通过此程序可以更好的实现LDPC码的仿真(in this passage we have write the program of edcoded and decoded of LDPC code.through it we can undersatand LDPC more.)

2维曲面拟合，gauss or gabor 函数(Functions to fit a 2D Gaussian or 2D Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit (sum of squared error) for many different choices of parameters then refining the most promising set of params through least-squares (exhaustive search followed by refinement). Least-squares is statistically equivalent to maximum likelihood estimation of the model parameters on the assumption of independent, normally distributed Gaussian noise in the observations (pixels). autoGaussianSurf(xi,yi,zi) fits a Gaussian,)

First optimal threshold is calculated. after that we get a pfa value. then plot snr vs pd
