一种OFDM系统中的频偏校正算法

A Frequency Offset Correcting Arithmetic for OFDM System

在简要地介绍了OFDM系统的基本原理后,给出了利用循环前缀相关特性的频偏校正算法,并给出了仿真结果。结果表明此算法简单易实现,克服了有些算法浪费资源的缺点,但同时也有同步范围较小等缺点。

First briefly introducing the basic theory of OFDM system, then the frequency offset correction arithmetic using the cyclic prefix, and the simulation result were given. It showed that the arithmetic could be easily achieved, and save the resource, but the extension of synchronization was less.
