摘要
OFDM是一种无线环境下的高速数据传输技术,具有很强的抗干扰、抗衰落能力及较高的频谱利用率。文章介绍了OFDM的基本原理和关键技术,建立了基本的OFDM系统模型,应用MATLAB对其仿真,分析了不同信道、不同技术下系统的误码特性。
OFDM is a kind of high speed data transmission technology in wireless environment.lt has anti-jamming and anti-multipath capability and high utilization of the spectrum.Beginning with brief introduction for the basic principle and crucial technique of OFDM, this paper establishes the basic model of OFDM system and simulates by MATLAB.We analysis error rate of the system with different channel and technical.
