摘要：
Orthogonal Frequency Division Multiplexing based on Offset Quadrature Amplitude Modulation (OFDM/OQAM) systems are highly sensitive to Carrier Frequency Offset (CFO), especially in doubly selective fading channels. In this paper, by modeling the doubly selective channel with Basis Expansion Model (BEM), we prove the cyclostationarity of the received OFDM/OQAM signal in the presence of CFO. A blind CFO estimator is proposed based on the derived close-form second-order cyclic statistic. Analysis and simulation results demonstrate that the proposed estimator provides robust CFO estimation performance in OFDM/OQAM systems over doubly selective fading channels. © 2015 Journal of Communications.
