A maximum-likelihood (ML) scheme and a low-complexity estimation scheme are proposed by applying the probability density function of the cyclic prefix of OFDM symbols to the ML criterion. From simulation results, it is confirmed that the proposed schemes offer a significant FO estimation performance improvement over the conventional estimation scheme in non-Gaussian noise environments. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {8}, number = {6}, year = {2014}, pages = {860 - 862}, ee = {https://publications.waset.org/pdf/9998481}, url = {https://publications.waset.org/vol/90}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 90, 2014}, }
