fs1016 for speech compression

matlab最常用，最实用的程序代码，初学者必须要掌握的。重要！！！(matlab most commonly used and most useful code, beginners need to master. Important! ! !)

ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING PERFORMANCE CALCULATION OF BER MEASUREMENT..

说明：  基于宽带调制转换器的一个压缩感知技术，Matlab软件包，用于模拟系统的采样。(A compressed sensing technology based on wideband modulation converter)

是一分学习MATLAB 很好的教程，可以从中学到很多东西，简单易懂(A good learning MATLAB tutorial, you can learn a lot from, and easy to understand)

关于复杂网络的聚类系数算法，用matlab计算，矩阵为稀疏矩阵。(clustering_coefficients(A) returns the clustering coefficients for all vertices in A. The clustering coefficient is the ratio of the number of edges between a vertex s neighbors to the total possible number of edges between the vertex s neighbors. )

svm 的参数优化，利用交叉验证法选择最优参数c g，最终提高训练集的分类准确率,更好的提高分类器性能(Svm parameter optimization, the use of cross-validation method to the optimal parameter c g, and ultimately improve the training set classification accuracy，better improve the classifier performance)

利用matlab在概率的求解以及绘图上应用，有概率密度函数和条件概率求解的code(application of the matlab)

本代码是宽带DOA估计matlab代码，信号源是BPSK信号，采用一般线性阵列或均匀线性阵列接收，共涉及频谱已知和未知两种情况。并且各部分均单独编写了m函数。(This code is used to conduct DOA of a broadband signal. The signal source is BPSK, with a general linear array or uniform linear array. Each of these cases includes two kinds of known and unknown spectrum. And, an M function is written separately in each part. )

说明：  使用FFT分析三角波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(FFT analysis of the use of the triangular wave signal spectrum to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)
