communication modulation technique code

matlab程序将传递函数通过Z变换使其离散化，然后再把得到的脉冲传递函数改写成差分方程。便于接下来一步的C程序编程。(matlab program will transfer function Z-transform them through discrete, then put the resulting pulse transfer function of a differential equation rewritten. Facilitate the next step of the C programming.)

this file give different codes of modulation
