未来的移动互联网中OFDM技术浅析

Superficial analysis of OFDM which used in future mobile network

从发展的角度对未来移动互联网技术进行了探讨,介绍了基于无线环境的正交频分复用(OFDM)调制解调技术。剖析了OFDM离散傅立叶反变换/离散傅立叶变换(IDFT/DFT)及高效编码方法等关键技术。

This paper discuss the technology used in the future mobile network with developmental viewpoint,and introduce OFDM which base on the wireless environmental.This paper analyse some key technology that IDFT/DFT and high efficiency coding.
