Abstract (in Japanese) (See Japanese page) 
(in English) A frequency offset caused by a difference between the carrier frequencies at the transmitter and the receiver results in the inter-carrier interference owing to the collapsed orthogonality among the subcarriers of the received OFDM signal.
It is well-known that the Moose's algorithm can estimate the frequency offset based on the maximum likelihood criterion by using the characteristics of the long training signal consists of two successive OFDM signals based in the IEEE802.11a.
In this paper, we analyze estimation performances of the Moose's algorithm and propose an iterative method based on the Moose's algorithm in order to improve the estimation accuracy.
Moreover, the proposed iterative method can expand a possible range of the frequency offset estimation.
By computer simulations, we evaluate the proposed method in comparison with the conventional Moose's algorithm.
