IEEE GLOBECOM 2007-IEEE Global Telecommunications Conference, 2007•ieeexplore.ieee.orgIn this paper, we develop a two-stage hybrid channel estimation and ICI cancellation
structure for OFDM systems. The double selective channels are approximated by an
improved basis expansion model (BEM), which is more accurate than the conventional BEM
when the normalized Doppler frequency is smaller than one. Based on this improved model,
a new ICI cancellation scheme is proposed to reduce ICI impact. Simulation results show
that the framework performs well.
