Performance of Phase Lock Loop in fading channel

此matlab人工鱼群算法希望对初学者有所帮助(This matlab AFSA hope to help beginners)

this is a matlab for the PSNR. In this .m I have been using the PSNR to evluate the quality of the audio quality. Its a very useful way to do it.

BPSK仿真，Eb/N0=0:10,得出BER与Eb/N0的关系曲线，AWGN信道(BPSK simulation, Eb/N0 = 0:10, draw BER versus Eb/N0 of the curve, AWGN channel)

自相关法谱估计的程序，这是一种经典的方法，效果真心不错(Autocorrelation spectrum estimation procedure, which is a classic method, the effect is really good)

ldpc码的编码、解码、构造校验矩阵程序。MATLAB环境(ldpc Decoding)

对识别的指纹进行二值化处理，可以让指纹的纹路更清晰。(On binary fingerprint recognition processing, fingerprint patterns can be more clear.)

SVM方法的基本思想是：定义最优线性超平面，并把寻找最优线性超平面的算法归结为求解一个凸规划问题。进而基于Mercer核展开定理，通过非线性映射φ，把样本空间映射到一个高维乃至于无穷维的特征空间（Hilbert空间），使在特征空间中可以应用线性学习机的方法解决样本空间中的高度非线性分类和回归等问题。svm 程序，即支持向量机的代码。(The basic idea of SVM method are: the definition of the optimal linear hyperplane, and the search algorithm for optimal linear hyperplane by solving a convex programming problem. Then based on Mercer nuclear expansion theorem, through a nonlinear mapping φ, the sample space is mapped to a high-dimensional and even infinite dimensional feature space (Hilbert space), so that in the feature space can be applied to solve the linear learning machine method, the sample space The highly nonlinear classification and regression problems. svm procedures that support vector machine code.)
