ASK,FSK,PSK信号调制及用FFT法进行频率估计-ASK signal modulation and the FFT algorithm with frequency estimation

making exponential signal with matlab In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum). For example an FSK signal can not sim

这个是一个FSK调制解调MATLAB实现的程序,是简化版的,调制解调一起调试的~-This is a FSK modulation demodulation of the MATLAB program, is a simplified version, modem debugging together ~
