软件无线电——matlab，主要介绍软件无线电中一些MATLAB仿真(Software-defined radio- matlab, introduces some of the MATLAB simulation software-defined radio)

MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。(MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab can work inside.)

Turbo编译码程序，内含注释；信道编码经典程序 内含3GPP、LTE标准，已验证正确，适合学习(Turbo encode and decode, containing comments channel coding classic program Containing 3GPP, LTE standards, verified correctly for learning)

Genetic algorithm feature selection by using Logistic Regression

说明：  最小二乘支持向量机，用于进行函数的回归分析(Least squares-Support Vector Machine,Used for regression analysis of functions)

图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)

基于一个字嵌入水印0和1bit,原理是将图像转换到空间域后选择系数类嵌入水印，能抗打印扫描攻击(based on a word and embedding watermark 0 1bit, the principle is to convert the image into the spatial domain selection class watermarked coefficient, )

利用matlab搭建汽车泊车平台，打开摄像头检测泊车位置(Use matlab to build car parking platforms, open the camera to detect parking position)

一个常用的matlab图像区域生长程序，由给定的单个种子和阈值条件进行生长(Matlab image of a commonly used region growing process, from a given individual seeds and the growth of the threshold conditions)

斯坦福大学公开课第三课中涉及的局部加权线性回归，用matlab实现了在不同带宽下的对比(Stanford open class third lesson involved locally weighted linear regression, using matlab to achieve a comparison of different bandwidths)
