Query: Iterative Hybrid Precoder and Combiner Design for mmWave MIMO-OFDM
  Systems   This paper investigates the problem of hybrid precoder and combiner design
for multiple-input multiple-output (MIMO) orthogonal frequency division
multiplexing (OFDM) systems operating in millimeter-wave (mmWave) bands. We
propose a novel iterative scheme to design the codebook-based analog precoder
and combiner in forward and reverse channels. During each iteration, we apply
compressive sensing (CS) technology to efficiently estimate the equivalent
MIMO-OFDM mmWave channel. Then, the analog precoder or combiner is obtained
based on the orthogonal matching pursuit (OMP) algorithm to alleviate the
interference between different data streams as well as maximize the spectral
efficiency. The digital precoder and combiner are finally obtained based on the
effective baseband channel to further enhance the spectral efficiency.
Simulation results demonstrate the proposed iterative hybrid precoder and
combiner algorithm has significant performance advantages.
