在一个OFDM系统中,一大批正交、重叠,狭窄的subcarriers衰落、传递并联,除可用的传输带宽。分离的理论,subcarriers最小，这是一个非常紧凑的频谱利用率。OFDM主要是由于该系统如何处理多路径干扰在接收机。多路径生成

-In an OFDM scheme, a large number of orthogonal, overlapping, narrow band

sub-channels or subcarriers, transmitted in parallel, divide the available transmission

bandwidth. The separation of the subcarriers is theoretically minimal such that

there is a very compact spectral utilization. The attraction of OFDM is mainly due to

how the system handles the multipath interference at the receiver. Multipath generates
