对OFDM系统的研究

Study on OFDM System

在移动无线通信中,正交频分复用(OFDM)技术具有频带利用率高和抗多径能力强等优点,能提供高速率和高质量的通信服务。介绍了OFDM系统的发展概况,阐述了OFDM系统的基本原理、系统模型和结构,探讨了OFDM技术的优缺点。

In MRC（mobile radio communication）,OFDM（orthogonal frequency division multiplexing）,which possesses some advantages such as the high-usage of frequency band,and strong anti-multipath capability,etc.,can provide high-speed and high-quality communication services.This paper introduces the general development situation of OFDM system,expounds the basic principles,model and structure of OFDM system,and probes into the advantages and disadvantages of OFDM technology.
