摘要
正交频分复用(OFDM)是一种多载波宽带数字调制技术。相比一般的数字通信系统,它具有频带利用率高和抗多径干扰能力强等优点,因而适合于高速率的无线通信系统。文章详细分析了OFDM技术的实现原理,用MATLAB软件对OFDM的传输性能进行了仿真模拟并对结果进行了分析。
Orthogonal Frequency Division Multiplexing (OFDM) is a multi-career broadband modulation technique.The main advantages of OFDM versus other types of modulation are better use of the available bandwidth and better performance in multi-path environments compare to simple digital systems and it is adaptive to high-data-rate wireless communication systems. This paper presents an overview of OFDM technique and its implementation scheme and making use of MATLAB to simulate the transmission performance of OFDM. The results of computer simulation are also discussed.
