摘要

本文从OFDM信号的二倍钟采样出发

给出了一种载波偏差估计算法

该算法直接利用时域信号的采样来估计载波偏差

克服了频域实现算法受载波偏差影响大的缺点

使得算法在不同的载波偏移下具有相同的估计精度

载波偏差估计范围大

同时该算法充分利用信号的有效能量

估计精度高

优于采用循环前缀的算法;论文同时给出了算法性能的理论分析和计算机仿真结果.

Abstract

In this paper

we propose a new time-domain estimator for OFDM signal by using over-sample processing.The proposed estimator is able to achieve wider estimation range of carrier frequency offset with higher accuracy than cyclic prefix(CP)based estimator.And the results of computer simulation show the proposed estimator overcomes the impact of carrier frequency offset and achieves the same accuracy regardless of the carrier offsets.
