摘要

提出了一种用于超宽带多频带正交频分复用(UWB MB-OFDM)系统的精细载波频偏估计方法。该方案利用了MB-OFDM系统中提供的频域扩展数据符号。为了证明所提出的CFO估计器的效率，在均方误差(MSE)和误码率(BER)方面与其他现有估计器进行了比较。

An Improved Residual CFO Estimation Scheme for UWB Multiband OFDM

In this paper, a fine carrier frequency offset (CFO) estimator is proposed for ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MB-OFDM) systems. The proposed scheme uses a frequency domain spreaded data symbol which is provided in the MB-OFDM system. To demonstrate the efficiency of the proposed CFO estimator, comparisons are made with other existing estimator in terms of mean square error (MSE) and bit error rate (BER).
