broadband multiuser-MIMO communication system, where
the co-channel users are equipped with multiple transmit
and multiple receive antennas. In particular, we propose
a joint coded two-step interference cancellation scheme
which effectively combats the effect of co-channel interference
(CCI) and inter-symbol interference (ISI) in multipath
channels. To overcome the peak-to-average-power ratio
limitation of multicarrier systems, the scheme employs
single-carrier frequency-domain equalization (SC-FDE)
based modulation combined with time-reversed space-time
block codes (TR-STBC). The receiver performs minimum
mean-squared error (MMSE) interference suppression at
the first stage, and then, CCI cancellation is implemented
with a bank of single-user channel decoders. Also, forward
error correction outer convolutional encoding, and random
bit interleaving are used to correct the carrier in deep fades.
To verify the utility of the proposed approach, the paper also
includes two sets of average symbol error rate simulations
for two different channel models. The first set is for a frequency
selective quasi-static fading channel while the second
set is for a Rayleigh fading channel modeled by a modified
Jakes’ model, both of which confirm the advantage of
the proposed scheme.
