OFDM是第四代移动通信的核心技术,正越来越受到人们的关注.在介绍OFDM基本原理的基础上,利用Simulink建立了一个基于OFDM技术的系统仿真模型.仿真结果表明:此系统能够很好地模拟OFDM传输系统,为进一步深入研究OFDM通信系统提供了便利.%OFDM is the key technology of 4G in the field of mobile communication, just and more and more be subjected to peoples concern. This paper introduces the basic principles of OFDM, establishes a system of simulation model baesd on OFDM technology by using Simulink. The simulation results show that the proposed model to the transmission system of OFDM is good , and this model also provides convenience for researching OFDM communication system in the future.
