摘要
正交频分复用(OFDM)是一种具有巨大潜力的传输技术。OFDM技术最突出的优点是频谱利用率高、抗干扰、抗信道衰落。本文首先介绍了OFDM技术的基本原理,接着分析了OFDM技术的优势以及需要克服的缺陷,最后讨论了OFDM的几种关键技术。
OFDM(Orthogonal Frequency Division Multiplexing)is a kind of transmission technology having huge potential.It has prominent advantages in high spectrum utilization,anti-jamming and anti-fading channel.This paper introduces the key techniques of OFDM and then analyzes the advantages of OFDM and the need to overcome the defects,and finally it focuses on studying several key techniques of OFDM.
