Abstract
In this paper, a new improved CFO tracking algorithm for OFDM systems is proposed. It is based on the fact that energy on virtual subcarriers could be quadratic or trigonometric with CFO estimation errors when it´s small, so the CFO can be estimated by coarse search and interpolation. Simulation results suggest that performance of the proposed method is equivalent with enumeration method while the computation burden of the proposed algorithm is only ten percent of the latter´s.
