此程序和fn_DBn_2D程序是一起的，用于测试fn_DBn_2D程序的分解和重构效果，里面用到了一副典型图象：babala。(This procedure and the procedure is fn_DBn_2D together for testing procedures fn_DBn_2D effects of decomposition and reconstruction, which uses a typical image: babala.)

说明：  基于Matlab的QPSK算法仿真，包含了算法结构，仿真图形等，仿真了通信过程中的调制过程。(Matlab simulation based on the QPSK method, including the algorithm structure, graphics, simulation, simulation of the communication process in the modulation process.)

对获得的512维小波特征进行了PCA降维处理，将特征空间降至100维，并采用前面得出的最佳系数针对多项式核函数和高斯径向基核函数(On access to the 512-dimensional wavelet features to reduce the dimension of the PCA, will feature space to 100 dimensions, and using the best coefficients obtained for the previous polynomial kernel function and Gaussian radial basis function)

this is an matlab version of remobval of normal noise

主要介绍如何实现卷积和相关的界面演示，并可以自己编写信号，操作方便。(Describes how to implement convolution and correlation of the interface presentation, and you can write your own signal, easy to operate.)

说明：  matlab xfem 插件，可用于计算多裂纹交叉融并结果(Matlab XFEM plug-in can be used to calculate the results of multi crack cross fusion)

脉动风时程matlab程序,风荷载时程曲线的matlab代码，自己找了好久，加上自己的修改，很简单。(Fluctuating wind schedule matlab, the wind load process curve of matlab code when, for a long time, and their own )

the function which finds fault location

求频谱的程序，可以对求出时域信号的频谱。适用于时域信号分析。(Determining a spectrum of the procedures, the time-domain signal is obtained spectrum. Applies to the time-domain signal analysis.)
