AddNoise_A

神经网络matlab训练网络和测试网络程序(Matlab neural network training networks and network testing procedures)

说明：  很有 用的LDPC译码程序，大家可以看看,很有借鉴作用(ldpc decoder)

采用MATLAB对常见插值 和拟合算法进行变成，并附有PPT文档说明(Using MATLAB and the fitting of the common interpolation algorithms become, along with documentation PPT)

OFDM系统，包括自适应功率和比特的分配，通过matlab实 现(OFDM systems, including adaptive power and bit allocation, by matlab )

自写曲率计算函数 ,关于非线性离散系统辨识，包含位置式PID算法、积分分离式PID。( Since writing the curvature calculation function, Nonlinear discrete system identification, It contains positional PID algorithm, integral separate PID.)

说明：  这是一部关于学习Matlab7.0版的编程书籍，比其他版本更详细(This is a version of the program on learning Matlab7.0 books, more than any other version)

通过移动机翼，尾翼，起落架和油箱的位置来使气动中心和重心重合。(By movingwings, tail, landing gearand fuel tankpositionto makethe aerodynamic centerand center of gravitycoincide.)

gui界面，读取xlsx中特定sheet，sheet中最后一列为y，前n列为x1-xn，线性拟合为y=b0+b1x1+...+bnxn，显示公式和残差的标准差(The GUI interface reads the specific sheet in xlsx, the last row in sheet is y, the former n is x1-xn, and the linear fitting is y=b0+b1x1+ (+bnxn), showing the standard deviation of formula and residuals.)

基于LMS的双向回波削除源码，不过回波幅度不要大于0.2,否则算法认为DOUBLE TALK DETECT。各位可修改此阀值，试试效果(based on the two-way LMS Echo slashing source, but not greater than the rate Echo 0.2, or that the algorithm** DOUBLE TALK. You can modify this threshold, try Effect)

可以实现对数据的宝华和姜维处理，是很多忙信号处理算法之前十分必须的(it is very impontant to do BSS)
