SNR-PCA

this is small ofdm simulator

这是一个关于PSK和LDPC码相结合的运用程序，很有参考价值。(This is an LDPC code on the PSK and the use of a combination of procedures, a good reference.)

Automatic Gray-Scale Image Thresholding methods: Tsai, Prewitt, Rosenfeld, Otsu, Kittler, Ridler.

说明：  RD成像雷达干扰，基于MATLAB的成像算法，有关雷达干扰欺骗模型，sar成像，多普勒雷达(Rd imaging radar jamming, imaging algorithm based on MATLAB, radar jamming deception model, SAR imaging, Doppler radar)

此文件包含大量matlab例程，尤其适合初学者，当学习资料在适合不过(This file contains a lot of matlab routines, especially for beginners, but when learning materials in a suitable)

Image water marking using DWT with 3-levl decomposition

数学建模基础教程，对于初学者可以参考，很好的基础建模资料(mathematical modeling basic course for beginners can reference, very good base modeling material )

封装好的模块是PV（光伏电池），本例利用斜坡信号作为电压端输入，仿真出光伏电池的外特性。(The packaged module PV (photovoltaic cells), in this case the use of the ramp signal as the input voltage terminal, simulation of the external characteristics of the photovoltaic cells.)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)

说明：  把训练数据拷入，load的*.m文件中, 文件中部load的*.m为测试数据 save 存盘的文件为测试数据的bp预测值, 该程序可以扩充n个输入,n个输出,很容易 (Copyed the training data, load the*. m file, the central load of*. m files for test data, save the file to save to disk bp predictive value of test data, the program can be expanded to n inputs, n outputs, it is easy)
