摘要 OFDM技术以其高的频谱利用率和良好的抗多径干扰能力,被看作是3G以后移动通信的主流技术。本文介绍了正交频分复用(OFDM)的基本原理、关键技术及优缺点,最后还对OFDM的应用前景进行了展望。 Due to its high spectrum utilization and good capability of preventing muti- path interference,OFDM is regarded as the core technology in Beyond 3G mobile communication system. In this paper, the basic principles,the core technologies and the analysis of the advantages and disadvantages of OFDM are introduced. Finally the application prospects of OFDM are also presented.
