用MATLAB实现对图形图像的处理，对图像的锐化。(Achieved using MATLAB image processing of graphics, the image sharpening.)

QPSK在多径衰落和加性高斯白噪声下的性能仿真，对于通信方面比较有用！(QPSK simulation with Gray coding and simple Rayleigh multipath fading channel and AWGN added)

matlab和C交互程序，MATLAB计算，C设计界面。(interactive program of matlab and C,matlab is suitable for computing and C is suitable for interface design.)

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)
