用IGBT元器件进行的三相全控整流桥的仿真电路(Components used for the three-phase IGBT full bridge controlled rectifier circuit simulation)

其中给出了多种调制方式的调制及解调程序，对初学者有一定帮助。(Which gives a wide range of modulation of the modulation and demodulation process, has a certain extent, help for beginners.)

通过Fourier与Laplace逆变换，把时域图变成频域图，增强信号的可视性。(Through the inverse transformation of Fourier and Laplace, the time domain diagram is transformed into frequency domain graph to enhance the visibility of the signal.)

说明：  Mobile Robot Simulation by Matlab

psk ve qam nedir ne iş e yarar

画出地球，模拟不同时刻卫星位置，模拟用户位置，与可见卫星(Draw the earth, the simulation satellite location, different time simulated user s location, with the visible satellites)

SRAD filetr for speckle reduction .This filter is a variant of anisotropic diffusion which successfully removes speckle type noise from images.

说明：  本源码是基于遗传算法的多维函数值的优化计算，利用matlab仿真(The source is based on genetic algorithm optimization of multi-dimensional function value calculation, the use of matlab simulation)

bmp to Yuv, DCT transform and quantization 4x4 compression

二次采样以确定像素间的相关性，然后对两个采样结果同时嵌入水印，利用的是倒谱变换(second sampling to determine the correlation between pixels, then the two sampling results also embedded watermark, make use of Cepstrum)
