Abstract
The deployment of increasingly dense heterogeneous mobile
networks can create high levels of interference among users that, combined
with severely time-dispersive channels, can result in substantial performance
degradation. To cope with both effects, in this paper, we propose an
iterative block decision feedback equalizer (IBDFE) for single carrier (SC)
transmissions that makes use of the correlation between the interference
in the receiving antennas and minimizes the mean squared error (MSE)
of the detected symbols. Our analytic and simulated performance results
show that the proposed receiver can clearly outperform the conventional
IBDFE and the linear interference rejection combining (IRC) detector in
severely time-dispersive channels with strong cochannel interference.
