摘要

In this paper, two fast and accurate FFT-based frequency offset estimation methods for OFDM systems are proposed. We analyze and simulate proposed methods in both Gaussian and multipath fading channels, and compare the results with those obtained using well known Schmidl's method. The simulation results are presented in terms of Error Variance (EV). Both proposed FFT-based methods have significantly smaller EV than Schmidl's method in AWGN and Multipath static fading channel and the proposed FFT method-II also has smaller EV than Schmidl's method in multipath time-varying fading channel.
