OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )
