说明：  利用Matlab软件平台对JTC进行了图像识别仿真实验，得到了二维及三维相关输出图像，显示出尖锐的相关峰。仿真实验表明：联合变换进行图像识别中存在强烈的零级干扰，干扰信号是有用信号的7.14倍，输出结果不理想；采用功率谱相减法可以消除零级强干扰，进而提高了图像的识别能力。(Simulations of joint transform correlator (JTC) using Matlab is implemented, and the 2-D and 3-D drawings of the correlation image are obtained. In the simulation experiments, the sharper correlation peaks are showed. The result shows that strong disturbance of zero rank exists in the simulation of JTC, and it is 7.14 times stronger than the useful signal thus, the power spectrum subtraction is used to eliminate the strong disturbance, and the capacity of image recognition is improved.)

基于小波变换神经网络的车流量预测，含程序和数据。小波分析是针对傅里叶变换的不足发展来的，傅里叶变换是信号处理领域中应用最广泛的的一种分析手段，然而它有一个严重不足，就是在变换是抛弃了时间信息，变换结果无法判断某个信号发生的时间，即傅里叶变化在时域中没有分辨能力。小波是一种长度有限，平均值为0的波形，它的特点包括：（1）时域都具有紧支集或近似紧支集；（2）直流分量为零。小波函数是由一个母小波函数经过平移与尺寸伸缩得到，小波分析即把信号分解成一系列小波函数的叠加。(Vehicle flow prediction based on wavelet transform neural network)
