N2 - Orthogonal frequency-division multiplexing (OFDM) modulation provides a high data rate communication service. However, in mobile reception, a loss of sub-carrier orthogonality due to Doppler-spread leads to inter-carrier interference (ICI). This paper proposes a channel estimation scheme based on one-dimensional raised cosine interpolation. A time-domain raised cosine interpolation plus a frequency-domain raise cosine interpolator with adaptive roll-off factor can estimate the channel response very well in high-mobility environments.
