Description: 正交频分复用(OFDM)是第四代移动通信的核心技术,它是实现宽带无线通信和多媒 体业务发展的基础。对OFDM 技术的基本原理，关键技术以及实现进行了研究，并且通过 matlab 中的通信仿真系统simulink 对OFDM 系统进行了模拟和分析，直观和形象地得到了 OFDM 系统在时域和频域的传输性能，得出的结果表明OFDM 系统可以明显地表现出抗多 径效应引起的频率选择性衰落和提高了频谱利用率，这一特性使得它能够在高数据传输速率 的无线信道中发挥优势。-Orthogonal Frequency Division Multiplexing (OFDM) is the fourth generation mobile communication core technology, which is broadband wireless communications and multimedia development. The basic principle of OFDM technology, key technology and implementation have been studied, and by matlab simulink simulation system in the OFDM communication system was simulated and analyzed, intuitive, and get the image of the OFDM system in time domain and frequency-domain transmission performance , the results show that OFDM system can be apparent in the anti-multipath effect caused by frequency selective fading and improve the spectrum efficiency, this allows it to transmit at high data rate wireless channel advantage.
