ddssim

ofdm.m为主程序，可以运行，将得到迭加噪声之后的误码率曲线，并与理论QPSK加高斯白噪声误码率曲线比较，两者将重合(ofdm.m-based program, you can run, will be after the noise superposition error rate curve, and with the theoretical QPSK plus white Gaussian noise bit error rate curves, which will coincide)

说明：  利用MATLAB语言编写的腐蚀模拟程序，可以用于MATLAB软件的腐蚀计算(The corrosion simulation program written by MATLAB language can be used to calculate the corrosion of MATLAB software.)

此文档包含了matlab的常用语句，适合初学者入门使用(The document contains matlab common expressions, is suitable for beginners introduction use )

产生高斯分布的白噪声的方法. 数据输出格式为txt. 可以读取到其它程序中, 作为后续开放使用. (have a Gaussian distribution of white noise method. Data output format txt. Can be read into other procedures, As a follow-up opening.)

DIGITAL IMAGE WATER MARKING USING DCT

基于卡尔曼滤波的GPSINS信息融合，，超强功能，可实现(Based on GPS/INS information fusion kalman filter, and strong function, can be realized)

粒子群优化算法。这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。(Particle Swarm Optimization. This program is the most basic particle swarm optimization program using Matlab, very simple. Only a few dozen lines of code.)

这里有卡尔曼滤波原理及公式陈列，编程实现，外加外界白噪声的影响，旨在加强对卡尔曼滤波的直觉理解与应用。(There Kalman filter theory and formula display, programming, plus white noise of the outside world to enhance intuitive understanding of the Kalman filter and its application.)

二维FDTD仿真高斯脉冲的传播，设定了不同PEC边界条件，并且可以自动生成.avi文件播放。(Propagation of two-dimensional FDTD simulation Gaussian pulse, set a different PEC boundary conditions, and can automatically generate .avi file playback.)
