OFDM完美出图，信噪比，16QAM星座图，加窗信号时域和频域波形图-Perfect figure, OFDM SNR, 16 qam constellation diagram, add window signal time domain and frequency domain waveform figure

该程序包括了ofdm和qam两种调制的matlab仿真程序,很好的-The program includes two kinds of ofdm and qam modulation of matlab simulation program, very good

QAM星座图，误码率，高斯白噪声，这是应用OFDM中的一个模块(QAM_MODEM Matlab code is Realize QAM modulation function and QAM demodulation function code)
