摘　　要：通过对OFDM信号模型和无线多径衰落信道模型的分析,本文建立了一种基于OFDM的毫米波通信系统的多径信道模型,给出了基于OFDM的毫米波通信在无线多径衰落信道下的仿真分析方法。通过该分析方法进行了多径衰落信道下毫米波通信系统性能仿真,得到了基于OFDM的毫米波通信相比单载波调制通信系统在无线多径衰落信道下具有更好的抗多径优势的结论,为毫米波通信系统的设计提供了重要支撑。Through the analysis on OFDM signal model and wireless multipath fading channel model,a multipath channel model of millimeter wave communication system based on OFDM is propsed in this paper;and a simulation analysis method of millimeter wave communication based on OFDM in wireless multipath fading channel model is also given.Adopted this analysis method,the performance simulation of millimeter wave communication system in multipath fading channel is carried out.And the conclusion shows that the millimeter wave communication system based on OFDM compared with single carrier modulation communication system has better anti multipath advantage in wireless multipath fading channel,which provides an important support for the design of millimeter wave communication system.
