stbc ofdm implementation using matlab code

一个是用matlab实现指纹识别程序。里面附带指纹图片，并用其作为例子实现指纹图像的匹配。(One is to use matlab to achieve fingerprint identification procedure. Which comes with the fingerprint image, and use it as an example to achieve the matching fingerprint images.)

基于MATLAB的OFDM仿真程序，仿真模块包括BPSK,QPSK,16QAM,64QAM(MATLAB simulation program based on the OFDM simulation module including BPSK, QPSK, 16QAM, 64QAM)

在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)

本程序是写的是扩展高斯（EGF）滤波器，当两个输入为根号1/2的时候就是IOTA滤波器，用于通信系统发端的波形塑形(This function calculates a filter with egf characteristic)

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.)

三维模型数据中包含“Princeton Shape Benchmark dataset”，三维模型数据库，其中的.off文件为三维模型，这些模型可以使用文件夹中的“打开三维模型的软件”打开查看。 matlab代码中“读取三维模型”为matlab读取.off文件的代码，得到的是三角面片信息和点云坐标 “三维模型切割”中为切割三维模型的一个例子，具体是从三维模型上找三个点构成一个平面，找到这个平面与三维模型的交点，这只是一个例子，具体如何切割三维模型需要自己实现，其中读取的三维模型为.obj格式，实验时需要把这部分换成上面读取.off的代码。运行其中的cut.m和cut2.m文件 “CBSM特征提取”用于提取形状特征，a.m是批量提取的，b.m是提一张图片的(3D model data contained in the Princeton Shape Benchmark dataset , the three-dimensional model , which .off file three-dimensional models that can be used in the folder open a 3D model of software Open View. matlab code reads the three-dimensional model for the matlab code to read .off file to obtain a triangular facets information and coordinate point cloud Three-dimensional model of cutting as an example of cutting three-dimensional model, in particular to find a three-dimensional model the three points form a plane, find the intersection of the plane and three-dimensional model, this is just an example of how to cut specific need to implement three-dimensional model wherein the three-dimensional model is read .obj format, experiments need to replace this part of the above read .off code. Run one of the cut.m and cut2.m file CBSM feature extraction is used to extract the shape feature, a.m bulk extraction, b.m is to provide a picture o)
