摘要 OFDM(正交频分复用),把信道分成许多正交子信道,减少了子信道间干扰,提高了频谱利用率。时域同步是OFDM系统中的关键问题,论文简要论述了时域同步的两种方法及基于IFFT/FFT的OFDM系统,并展望了OFDM的应用前景。 OFDM(Orthogonal Frequency Division Multiplexing) separates the communication channel into many orthotropic sub_channels so as to decrease the inter_sub_channel interferences and increase the utilization of frequency spectrum.This paper presents two methods for time domain synchronization,a key problem of OFDM,and the system based on IFFT/FFT.It also prospects the application of OFDM
