本程序中得到的收端OFDM信号的频谱波形，是与其发端信号的排步有关的。在发端的
％ 载波安排上，128个载波有前后各32个载波是null载波(如果这前后各32各载波是带外频段，
％ 那么理论上它们都应该是零！)，中间的64个载波是数据载波。这样的排步很明显就是一个
％ 两边低，中间高的频谱形式。所以，收端也应该是这个轮廓。

由MATLAB程序产生2Gbi/s的基带OFDM信号先将2^15-1个伪随机序列映射到256个进行4QAM编码调制的子载波上，编码后的OFDM符号再经过IFFT变换将其转换为时域波形，接着添加6.4ns的循环前缀（CP），产生的数据波形再装载到Tektronix任意波形发生器（AWG）中，产生2Gbit/s的基带OFDM信号。基带OFDM信号频谱示意图如图3所示。其中包括256个OFDM子载波256个子载波中200个子信道用来传送数据信号，27个高频和28个低频子信道为了过采样的需要置0，OFD
