摘要

本文研究了正交频分复用(OFDM)系统中整数频偏(IFO)估计的一种简便方法。通过将传统的极大似然估计器改进为两阶段估计策略，推导出IFO估计器。仿真结果表明，与ML估计器相比，所提出的IFO估计器具有较好的鲁棒性。

Improved Pilot Symbol-Assisted Estimation of Integer Frequency Offset for OFDM

This paper deals with a simple way of estimating the integer frequency offset (IFO) of orthogonal frequency division multiplexing (OFDM) system. By modifying the conventional maximum likelihood (ML) estimator to have two-stage estimation strategy, the IFO estimator is derived. Simulations indicate that the proposed IFO estimator works robustly when compared to ML estimator.
