Abstract :
A new kind of equalization scheme of SC-FDE system is proposed in this paper, which uses the distribution differences of residual inter-symbol interference between conventional FDE-NP decision feedback equalization and reversed FDE-NP decision feedback equalization to reduce the residual ISI caused by multipath channel. The feedback coefficients of reversed FDE-NP equalizer are conjugate with that of the conventional FDE-NP equalizer. The simulation results show that this method can improve the detection performance of SC-FDE system in multipath channel.
