摘要

针对平坦衰落信道，提出了一种改进的单频估计方法。与基于自相关函数的传统估计器相比，所提出的载波频偏估计器减少了自相关函数计算中的计算次数。结果表明，该估计器比现有的估计器具有更好的性能。此外，所提方法的性能已被观察到非常接近Cramer-Rao下界(CRLB)。

An Improved Autocorrelation Based Single Frequency Estimator with Reduced Complexity

This paper proposes an improved single frequency estimator for flat fading channels. The proposed carrier frequency offset (CFO) estimator decreases the number of computations in the calculation of the autocorrelation function (AF) when compared to AF-based conventional estimators. The results shown that the proposed estimator achieves better performance than the existing estimators. Furthermore, the performance of proposed method has been observed to lie very close to the Cramer-Rao lower bound (CRLB).
