create a structure element to use in the mathematical morphology

image watermarking method

将矩阵中的元素替换写成function后，带入主程序运行的Matlab源码(Will replace the matrix elements after written function, into the main program running Matlab source)

说明：  信噪比从0～13 dB，每隔1 dB仿真得到二进制双极性码的误码率(The bit error rate of binary bipolar codes is simulated every 1 dB from 0 to 13 dB.)

CORDIC sin cos algorithm 2

problems of optical communications

说明：  使用非线性共轭梯度法求解优化问题，使用matlab编程求解，是最优化方向的基本代码(Using nonlinear conjugate gradient method to solve the optimization problem and MATLAB programming to solve it is the basic code of the optimization direction)

数字通信系统中，基于MATLAB的几种常见信号的仿真(Digital communication system, based on several common signal MATLAB simulation)

该压缩包实现二维的DCT变换和逆DCT变换，可以对图像做DCT变换和逆DCT变换，实现非常简洁，速度很快。(the compressed 2D DCT and the inverse DCT. Images can be done DCT and inverse DCT achieve a very simple, very fast.)

use system identification toolbox in MATLAB to identify and estimate the model
