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。 (this process the resumption end of the spectrum OFDM signal waveform, with the originator of the signal further on the row. The originator% carrier arrangements, 128 of the carrier after a 32 carrier is null carrier (if it was around the 32 is the carrier frequency band. % then theoretically they should be zero!) the middle 64 carrier data carrier. This arrangement is obviously further 1% lower on both sides, in the middle of the spectrum form high. Therefore, the admission should end this profile.)
