matlab在通信原理中的应用，信道编码卷积码仿真，希望大家能用得上！(matlab in Communication Theory in the application of channel coding convolutional code simulation, hope that we can useful!)

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

离散时间信号的傅立叶变换的各个例子的算法，很不错的，希望对大家有用(discrete-time signal Fourier Transform algorithm examples, very good, we hope to useful)

用遗传算法求一维函数极值，Matlab语言，可用作学习参考！(Genetic algorithm for extreme one-dimensional functions, Matlab language, can be used as a reference. . .)

This is an implementation of local binary pattern with some results

说明：  Matlab数值计算，回归分析，多元线性回归，Matlab统计工具箱的使用(Matlab numerical calculation, regression analysis, multivariate linear regression, statistical Matlab Toolbox use)
