OF123456
OF,实际上OF是MCM Multi-CarrierModulation,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。在向B3G/4G演进的过程中,OFDM是关键的技术之一,可以结合分集,时空编码,干扰和信道间干扰抑制以及智能天线技术,最大限度的提高了系统性能。(OF)
