FM stereo signal simulation

是FM调频立体声的调制解调的matlab仿真代码，实现了对双声道语音的调制和解调，非simulink方式，完完全全的matlab代码 This is for FM stereo radio signal modulation and de-modulation code. it is not for matlab simulink, it is completely matlab code, you can follow it and for understanding FM stereo signal generate very well.
