Abstract
Influence of Doppler shift and ICI are the focus of the paper. Newly proposed systems must provide a high mobility level compare with 802.11 standard and support low subcarrier frequency spacing. Moreover, for the higher carrier frequencies and mobile speeds, the influence for Doppler shifts will be large and therefore, the influence of ICI becomes severer. BER performances in such multipath and multiple Doppler shift environment obtained with decision feedback equalizer (DFE) and a newly proposed turbo equalizer (TE) estimated with the aid of computer simulation. The proposed TE provides better ICI suppression than does the DFE at the same level of complexity
