Abstract

Turbo equalization schemes based on minimum mean square error (MMSE) criteria available in the literature are computationally involved as they require some form of matrix inversion. In this paper, we propose a low complexity turbo-equalization scheme with successive interference cancellation (TE-SIC) for the equalization of doubly dispersive channels for orthogonal frequency division multiplexing (OFDM) based receiver systems where the matrix inversion is eliminated completely. TE-SIC leverages on the soft feedback symbol estimation to remove the Inter-carrier Interference(ICI) from the received data thus eliminating matrix inversion. Numerical simulation results show that TE-SIC performs better than other schemes of comparable computation complexity at signal to noise ratios (SNR) of practical interest.
