这封信的目的是提出一种新的载波频率偏移（CFO）估计在直流偏移（DCO）的存在，基于导频的周期性。新的CFO估计器可以在低复杂度下获得令人满意的性能，而不考虑DCO的存在。随后的分析和数值模拟验证了该估计器的优越性。
The purpose of this letter is to propose a novel carrier frequency offset (CFO) estimator in the presence of DC offset (DCO), based on the pilot's periodicity. The new CFO estimator can achieve satisfactory performance at low complexity, irrespective of the DCO presence. The superiority of the proposed estimator is verified by the subsequent analysis and numerical simulations.
