Abstract	In this paper, an frequency offset estimation scheme for orthogonal frequency division multiplexing (OFDM) based packet communication systems is proposed, in which allocated powers of the short training symbols and long training symbols are different while maintaining average power of overall preamble sequence. The preamble structure considered is based on the preamble specified in IEEE802.11a and IEEE802.11p standardization group. From the simulation results, it is shown that the proposed scheme can achieve better mean squared error (MSE) performance for frequency offset estimation error than the conventional scheme.
