PCA人脸识别

说明：  线性神经网络，BP神经网络，Hopfield神经网格，Elman神经网络，RBF神经网络；在模型应用模块中实现了六种实际应用：RBF网络的船用柴油机故障诊断，BP网络的齿轮箱故障诊断，SOM网络的回热系统故障诊断，BP网络的设备状态分类器，SOM网络的人口比例样本分类，SOM网络的土壤性状样本分类。(Linear neural network, BP neural network, Hopfield neural network, Elman neural network, RBF neural network application modules in the model to achieve practical application of Six: RBF network of marine diesel engine fault diagnosis, BP network gearbox fault diagnosis, SOM network regenerative system fault diagnosis, BP network classifier equipment, SOM network the proportion of the population sample classification, SOM network classification of soil samples.)

图像的几何矫算法及其用MATLAB实现的代码，内容全面，包含图片(The geometry of the image by algorithm and MATLAB code, comprehensive, including pictures )

此代码基本上是为了学习的目的，是学习的概念，信道估计，噪声与不同的方差和概率误差计算。我创建了一个采用BPSK使用比特序列总长度是1000位，在噪声信道传输和接收。在接收比特误码率后，再对不同的噪声进行重复，并对不同的噪声进行重复计算。最后，我们比较了所有通道的性能，这将有助于你清晰地清楚你的噪声，信道，错误的概率，检测和估计的概念。谢谢
