摘要
正交频分复用(OFDM)技术是当今高速无线通信领域中的研究与应用热点,它具有抗多径衰落、频谱利用率高、采用自适应调制等优点,被普遍认为是宽带无线接入和第四代移动通信系统中的关键技术之一。首先对OFDM的基本原理进行了介绍,接着重点对此技术的优点和缺点进行了分析,随后对其技术发展现状进行了分析,并对其发展作出了展望。
OFDM （Orthogonal Frenquency Division Multiplexing） is a popular topic of research and application in high speed wireless communication field, and generally regarded as one of the core technologies in the 4th mobile commtmication system due to its good performance of antimulti-path fading, high frequency efficiency and self-adaptation modulation. In this article, it introduces first the basic principles of OFDM, then gives the analysis of its advantages and disadvantages, analyses the actualities of development on OFDM, and finally brings forward the prospect of this technology.
