摘要 正交频分复用(OFDM)应用在移动通信系统中时,信道多普勒效应造成的载波间干扰(ICI)是引起性能 下降的重要原因.本文分析了信道多普勒效应引起OFDM ICI的机制.基于输出多普勒扩展函数输入输出关系,给出一 种接收信号结构的三维图形表示,并提出一种的计算连续多径信道中OFDM任意子载波上ICI的简单方法. Performance degradation due to Inter-Carrier Interference (ICI) resulted from channel Doppler effects is significant for Orthogonal Frequency Division Multiplexing (OFDM) when used in mobile communication systems. In this paper,the mechanism of OFDM ICI caused by Doppler effects is discussed. Based on the I/O relationship of channel output Doppler-spread function, a 3-di-mensional graphic form for visualizing the received OFDM signal structure and a simple method for calculating ICI levels of arbitrary subcarrier in channels,esp. with a continuum of multipath components,are proposed.
