In OFDM transmission, a loss of sub-carrier orthogonality due to Doppler-spread of the channel leads to a performance degradation caused by inter-carrier interference (ICI), especially, in mobile reception environments. To overcome this problem, an ICI canceller is very effective. This paper proposes a scheme that improves the performance of the ICI canceller that we have proposed elsewhere. The accuracy of the channel estimation is improved by reducing the influence of ICI. Consequently, the performance of the ICI canceller is improved to nearly an ideal level.
