when local carrier absolute frequency offset equals half of consecutive subcarrier frequency spacing at the transmitter, that is to say, when relative frequency offset reaches 50%, the probability of symbol error deteriorates to fifty percent.
当本地载波的绝对频偏达到发送相邻子载波频率间隔的一半,即相对频偏达到50%时,系统的误符号率恶化为50%。
The main character of this technique is the high-spectral constraint of each subcarrier which results in its non-sensitivity to frequency offset where OFDM enduring.
该技术的主要特点是各子信道具有很高的频谱约束性,对系统频率偏差不敏感,从而克服了OFDM易受频率偏差影响的弱点。
