摘　　要：在对OFDM系统各类典型的数据辅助的载波同步方法总结的基础上,提出了一种适于快衰落信道环境的载波频偏估计方法,算法分析及仿真结果表明该方法可以有效消除快衰落环境对载波频偏引起的误差,并可在多种移动环境下使用,此外,由于提出的算法相对较低的运算,可以适用于对功耗或体积有特殊要求的小型移动终端。Based on summarizing every typical method of the carrier frequency synchronization, in this paper a new frequency offset estimation algorithm on fast fading channels is presented. The analysis and simulation show that the algorithm can eliminate the error of the Carrier frequency offset caused by the fast fading channels and can be used in several mobile channels, meanwhile for the low computation cost of the algorithm it can be used in some small mobile terminals that have special demands to the power consumption or solidity.
