用matlab实现通信系统中的DPSK差分编码器的源代码(the matlab source code of DPSK)

解ABCD的四元方程求解ABCD的值，并通过此值计算出电力器件vto，rt的值，从而使并联器件变得简单，有效(Solution ABCD equation solving the value of the ABCD and power devices VTO rt value calculated by this value, so that the the parallel device becomes simple, effective)

This is a work-in-progress. Please check back for updates, and check software carefully before using!

SOOBEL OPERATORS filter to enhance the image

自己实现的一维、二维DFT。优点：变换后的低频分量在中间，弥补了matlab库函数的不足（高频分量在中间）(Realize their own one-dimensional, two-dimensional DFT. Advantages: low-frequency components after the transformation in the middle, made up for the inadequacy of matlab library function (high-frequency component in the middle))
