正交频分复用技术是近年来发展起来的新技术,在高速无线数据传输领域有很大的应用前景。文章在分析和总结相关文献的基础上,介绍了正交频分复用(OFDM)技术的发展历史,讨论了正交频分复用技术的基本原理和实现方法。通过分析表明,在高速无线通信中OFDM对于消除符号间干扰(ISI),降低系统的复杂度等方面具有很大优势。正交频分复用(OFDM)是一种多载波宽带数字调制技术,它能有效地克服传输中的多径干扰和消除码间串扰,适合于高速率的地面信道视频传输。本文就OFDM技术进行了较为详尽的分析,并对OFDM的传输特性进行了基于FFT算法实现的MATLAB软件模拟及模拟结果分析。 -OFDM is a new technology developed in recent years, high-speed wireless data transmission in the field of great applications. This paper analyzes and summarizes the basis of relevant literature, describes orthogonal frequency division multiplexing (OFDM) technology, history, orthogonal frequency division multiplexing discussed the basic principles and implementation methods. The analysis shows that in the high-speed wireless communication in OFDM symbol for the elimination of interference (ISI), and so reduce the complexity of the system has great advantages. Orthogonal frequency division multiplexing (OFDM) is a multi-carrier wideband digital modulation techniques, can effectively overcome the transmission of multi-path interference and the elimination of intersymbol interference, the ground for high-speed video transmission channel. In this paper, OFDM technology, a more detailed analysis, and transmission characteristics of OFDM FFT algorithm based on the MATLAB software simulation
