| Abstract: | In doubly-selective fading wireless channel,the conventional orthogonal frequency division multi- plexing(OFDM)receivers for inter-carrier interference(ICI)compensation require extensive computa- tions.To obtain an effective balance between performance and complexity,the whole channel response matrix was decomposed into a sequence of submatrix,and then a novel equalizer based on minimum mean square error(MMSE)criterion was presented to combat the ICI.Furthermore,a simple ordering-based decision-feedback equ... |
