samling using matlab

一种基于matlab的数字水印的仿真的实现。(Digital Watermarking Based on the simulation matlab implementation.)

说明：  在OFDM系统中最经典的信道估计方法是LS算法，采用MATLAB对LS算法的性能进行了仿真(OFDM systems in the most classical channel estimation method is LS algorithm, the use of MATLAB on the performance of LS algorithm simulation)

2*2 mimo-ofdm系统的误码率测量。经过时不变信道(ber of 2*2 mimo-ofdm)

感知器分类的一个例子，分成两类的分类器,用MATLAB实现(perceptron example for matlab)

Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)

随机场的估计和应用，是非常流行的图像分割的算法。(markov random field is very popular)

这个matlab程序可以同时对图像做高斯滤波和中值滤波处理。(The matlab program can do Gaussian image filtering and median filtering.)

OFDM implementation using 64QAM

PLS回归模型建立的程序，针对多输入和多输出的。希望此方法能对大家有帮助(PLS regression model program, multiple-input and multiple-output targeted. I hope this method can help everyone)
