摘要
OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术,是
MCM( Multi-CarrierModulation)多载波调制的一种。OFDM 作为一种具有很强的
抗多径衰落能力的调制解调技术,克服了 CDMA 技术在无线信道中传输高速数
据业务所遇到的瓶颈问题,即严重的码间干扰。为验证 OFDM 系统的优点,本
文介绍 OFDM 基本原理的基础上,分析 OFDM 系统的关键技术,并重点对 OFDM
系统进行了 MATLAB 设计与仿真。

Abstract
Orthogonal Frequency Division Multiplexing(OFDM) is a kind of multicarrier
digital modulation technique. OFDM, as a kind of Modem technology which has a
strong ability to resist multipath fading of demodulation. e bottlenecks of the
CDMA technology in the wireless channel transmission of high-speed data service
encounter, that is Severe intersymbol interference. To test and verify the advantages of
OFDM system. On the basis of introduction of the basic principle of OFDM,we
analysis of the key technologies of OFDM system, and focus on the OFDM system
design and MATLAB simulation
Keywords: OFDM; Modem Technology; Design and Simulation; MATLAB
