This paper combines basis expansion model (BEM) based channel estimation with Wiener filter to deal with channel estimation in various mobile environments, especially in high-speed cases. The expression of Wiener filter for BEM based channel estimation (WF-BEM) is derived and the result explicitly considers the effect of intercarrier interference (ICI). The simulation results show that WF-BEM is better than Wiener filter for least squares (LS) based channel estimation in time-varying channels.
