Modulation techniques. Matlab using and very user friendly

it is a file to watermark the image file in matlab

对椒盐噪声和噪声分别进行3种滤波,包括算术均值滤波、几何均值滤波、中值滤波(three kinds of filter to salt and pepper noise and gaussian noise ,including arithmetic mean filter, geometric mean filter, median filter)

matlab中的floyd算法，对数学建模有很大的帮助(floyd algorithm matlab in the mathematical modeling of great help)

相控阵雷达数字去斜仿真，发射信号和回波信号，混频滤波信号，正交解调，滤波器设计 使用带通滤波器，二次时延；两个目标(Phased array radar to ramp digital simulation, the transmitted signal and the echo signal, mixing the filtered signal, quadrature demodulation, filter design use a band-pass filter, the second delay two goals)

使用案例讲述了MATLAB的数据预处理，有源代码说明( Data preprocessing)

Description Applies ideal binary mask to noise corrupted speech signal. The processing takes place within an FFT based short-time spectral analysis-modification-synthesis framework. The ideal binary mask is computed from an oracle (true) signal-to-noise ratio (SNR) through thresholding with local SNR criterion. The routine returns synthesized enhanced speech, the ideal binary mask and the true instantaneous spectral SNR.

在matlab环境下对图像进行高通滤波和低通滤波处理。(The high-pass filter and low-pass filtering image processing in Matlab environment.)

matlab 读取文件中数据并绘制图形的程序(matlab draw the data from the other files)

相图与庞加莱截面，但程序有点问题，需要交流，相图应该是对的(A problem, the phase diagram and Poincare section)
