AbstractIn this paper, a novel frequency offset estimation technique for the OFDMA based WiMAX system is proposed. It is perceived that Mobile WiMAX based on the IEEE802.16e standard has an aperiodic preamble, hindering the most efficient frequency offset estimation techniques which are based on utilising the preamble's periodicity. In this paper, a novel technique for creating periodicity in the preamble by exploiting its design is proposed and evaluated. The results show that the proposed scheme has a significantly better performance than the currently used techniques.
