用matlab仿真ASK包络解调，程序完善，结果与理论值非常接近(Using MATLAB to simulate ASK envelope demodulation, the program is perfect, and the result is very close to the theoretical value.)

实现ask的调制解调过程，载波相乘实现调制，包络检波实现解调(Realizing the modulation and demodulation process of ask)

实现2ASK、2FSK调制及两者的包络检波解调(Implementation of 2ASK, 2FSK modulation and envelope demodulation of both)
