OFDM系统仿真，采用各种调制方式（BPSK，QPSK，QAM8，QAM16，QAM32，QAM64）,OFDM system simulation, using a variety of modulation (BPSK, QPSK, QAM8, QAM16, QAM32, QAM64)

本程序为通信系统中的数据调制，也就是数据映射，主要包含QPSK，QAM16，QAM64的调制和解调。-This procedure for the data communications system modulation, that is, data mapping, mainly includes QPSK, QAM16, QAM64 the modulation and demodulation.

16QAM,64QAM调制解调，以及星座图等部分-16QAM, 64QAM modulation and demodulation, as well as some other constellation
