摘　　要：正交频分复用（OFDM）技术是一种多载波调制（MCM）技术，是无线环境下的高速传输技术。OFDM能有效地对抗多径干扰和频率选择性衰落并且它具有较高的信道利用率。本文分析了OFDM实现的各种关键技术，详细讨论了如何利用Matlab／Simulink建立OFDM系统的仿真模型。最后，对比了仿真结果并对结果进行了分析。OFDM is a kind of multi-carrier modulation; it is also a kind of high speed transmission technology, in wireless communication. OFDM can effectively deal with multi-path interference and frequency selective fade and it has high channel utility. This paper analysis the key technologies of OFDM, and specifically discuss how to make use of Matlab/Simulink to simulate the system of OFDM. Finally, the results of simulation are given and analyzed.
