Abstract
In this paper, we propose a new time-domain estimator for OFDM signal by using over-sample technology. The proposed estimator is able to achieve wider estimation range of carrier frequency offset with higher accuracy than cyclic prefix (CP) based estimator. And the results of computer emulation show the estimator gets over the impact of carrier frequency offset and achieves the same accuracy in different offsets.
