摘要
正交频分复用(OFDM)是一种多载波宽带数字调制技术,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。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论进行了分析。
Orthogonal frequency division multiplexing （OFDM） is a multi-cartier broadband modulation technique. The main advantages of OFDM exist in better use of the bandwidth and better performance of antimuhipath interference and it is adaptive to high-dada-rate wireless communication systems. This paper analyzed OFDM technique and its implementation principle and made use of MATLAB to simulate the transmission performance of OFDM. The results of computer simulation are also discussed.
