Keywords: blind estimation; frequency offset; maximumlikelihood; non-Gaussian noise; OFDM.

Abstract:
In this paper, the blind frequency offset estimation schemes robust to the non-Gaussian noise for orthogonal frequency division multiplexing (OFDM) systems are addressed. Based on the cyclic prefix structure and a maximum-likelihood (ML) estimation, the estimation schemes in non-Gaussian noise are proposed. Simulation results show that the proposed blind estimation schemes offer a robustness and a substantial performance improvement over the conventional blind estimation scheme in non-gaussian noise environments.
