数字通信中经常用到的几种调制方式仿真，包括ASK调制，OOK调制，FSK调制，BPSK调制等，将该代码理解透彻能够对数字系统中的调制解调方式有着更深入的认识，绝对的好东西，有时间会效代码中的各条语句添加上注释-Frequently used in digital communication several modulation simulation, including the ASK modulation, OOK modulation, FSK modulation, BPSK modula

这是一个经典的OFDM程序，已经加了必要的注释，希望对初学者能有帮助。-This is a classic OFDM program, has been added not comment, we hope to help beginners.
