ofdm程序，关于信道估计算法的matlab程序(OFDM procedures, on the channel estimation algorithm matlab program)

一款RS缩短码的源代码，可修改其中主程序的数据变任意一种RS码的编码器，此程序经多次验证均正确，且采用标准代码格式描写，易读。(A shortened RS code source code, which can modify data in the main program code change any of the RS encoder, this procedure has been repeatedly verified are correct, and the use of standard code format description, easy to read.)

MImo detector , very useful for student

creates code of barras to bussines

多径衰落信道matlab仿真程序，有说明(multi-path flat fading)

dct隐写技术matlab实现资料。算法原理：通过在一个图像块中调整两个DCT系数的相对大小，隐藏秘密信息。 将载体图像分为8×8的块，做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if（要隐藏信息‘1’） make else make 逆DCT变换，还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

进行特征选择，利用权重进行特征选择，代码解释充分(Feature selection is carried out, feature selection is carried out with weight, and the code is fully interpreted.)

说明：  FIPSO算法，全信息粒子群算法，用于求解一些函数的最优值问题(fully informed particle swarm, a kind of particle swarm)

此书是关于数字信号处理的一些算法收集，很详细，全面。(This book is about the digital signal processing algorithms to collect some very detailed and comprehensive.)

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值，所有比阈值亮的像素转换为白色；而所有比阈值暗的像素转换为黑色。 (The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)
