This paper considers the design of hybrid precoders
and combiners for mmWave MIMO systems with per-antenna
power constraints and the additional limitations introduced by
the phase-shifting network in the analog processing stage. Previous
hybrid designs were obtained using a total power constraint,
but in practical implementations per-antenna constraints are
more realistic, specially at mmWave, given the large number of
power amplifiers used in the transmit array. Assuming perfect
channel knowledge, we obtain first an approximation to the alldigital
solution for the precoder and the combiner given the
per-antenna constraints. Then, we develop a new method for the
design of the hybrid precoder and combiner which attempts to
match such all-digital approximation. Simulation results show
the effectiveness of the proposed approach, which performs close
to the all-digital solution.
