MMSE最小均方误差均衡仿真 可以方便的运行(MMSE matlab)

参照3GPP标准，基于用户分布的3D波束赋形方案的研究(Referring to the 3GPP standards, research users distributed 3D beamforming scheme based)

This paper presents a novel algorithm of hiding secret messages by applying mathematical lemmas and information theory. The proposed algorithm can hide more information with acceptable embedded rate and achieves requirements of information hiding algorithm and simply information extracting. The main idea is applying modern algebra to solve the information hiding problem in multimedia. In order to prevent some attacks on stganography, hidden initial bits of image data pixels are chosen randomly. The extracted information are achieved without the reference of the original image and extracted keys. The experiment results show that our approach is effective and reliable.

OFDM SIMULATION HOW TO CREATE A OFDM SIGNAL

lda基本思想是选择使得Fisher准则函数达到极值的向量作为最佳投影方向，从而使得样本在该方向上投影后，达到最大的类间离散度和最小的类内离散度(Linear classification algorithm)

说明：  直方图添加与去除椒盐噪声和高斯噪声并进行对比，以及直方图均衡化的matlab程序实现代码 (Add the histogram and remove the salt and pepper noise and Gaussian noise and contrast, and histogram equalization matlab program code)

在ar人脸库上实现Direct Fisher discriminant analysis,该方法首先对类内散布矩阵对角化，然后对类间散布矩阵对角化，使类间散布矩阵对角化的矩阵即使鉴别向量集(In the ar face database to achieve Direct Fisher discriminant analysis, this method first within-class scatter matrix diagonalization, and then between-class scatter matrix diagonalization, so that between-class scatter matrix diagonalization of the matrix even if the identification of a vector set)
