  This letter investigates bit-interleaved coded multiple beamforming (BICMB)
with perfect coding in millimeter-wave (mm-wave) massive multiple-input
multiple-output (MIMO) systems to achieve both maximum diversity gain and
multiplexing gain. Using perfect coding with BICMB enables us to do this. We
show that by using BICMB and perfect coding, the diversity gain becomes
independent from the number of transmitted data streams and the number of
antennas in each remote antenna unit (RAU) at the transmitter and the receiver.
The assumption is that the perfect channel state information (CSI) is known at
both the transmitter and the receiver and the number of antennas goes to
infinity. This latter assumption can be relaxed by a large number of antennas
in each RAU, similar to the case for all massive MIMO research. Simulation
results show that when the perfect channel state information assumption is
satisfied, the use of BICMB with perfect coding results in the diversity gain
values predicted by the analysis.
