Abstract

We investigate the asymptotic performance of a multiple input/multiple output (MIMO) decision-feedback equalizer (DFE) used to detect a multicarrier signal transmitted without guard time over a linear dispersive channel. We design the MIMO DFE for a minimum mean square error criterion (MMSE) and compare its performance to that of a single carrier system also using an infinite length MMSE DFE equalizer. We demonstrate that both uncoded systems achieve the same capacity
