Abstract :
In this paper, a frequency domain implementation of a block-wise space-time turbo equalizer is presented where InterSymbol Interference and Multiple Antenna Interference are dealt with separately. Thanks to this functional split, we also introduce a low complexity turbo equalizer based on a Matched Filter approximation of the T-dimensional equalizer from a given iteration. Considering a Space Time -BICM transmission scheme over a MIMO ISI channel, simulations show that our equalizer is able to outperform in performance the conventional approach inspired by Wang and Poor´s.
