Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an accuracy improvement method of a carrier interferometry (CI) based channel estimation technique for dynamic parameter controlled orthogonal frequency and time division multiple access (DPC - OF / TDMA) systems under high mobility conditions. In the proposed scheme, we estimate channel state information (CSI) for each time slot by applying weighted averaging on both the frequency and time domains. Moreover, to improve tracking accuracy to channel variation, we extrapolate CSI for each time slot using the estimated CSI sequence. Computer simulation confirmed that the proposed scheme can achieve high accuracy of estimated CSI under high mobility conditions.
