Query: A Comprehensive Performance Analysis for mm-Wave Massive MIMO Hybrid
  Beamforming under PA Nonlinearities   In this paper, we develop a framework to investigate the performances of
different hybrid beamforming architectures for massive multiple input multiple
output (MIMO) systems impaired by power amplifier (PA) nonlinearities. Indirect
learning architecture based on feedback after anti-beamforming is adopted in
design of digital pre-distortion (DPD) in order to compensate the nonlinear
distortion caused by PA. In addition, we propose a novel analog beamformer
design for partially connected architecture based on generalized
eigen-beamformer (GEB) approach. In literature, the effects of nonlinear PA's
on the out-of-band (OOB) radiation and achieved signal-to-interfence-plus-noise
ratio (SINR) are investigated. However, these studies are limitted to fully
digital or partially connected hybrid beamforming architectures while deploying
Bussgang decompostion on a PA basis without considering the array architecture
type in performance analysis. In this study, we derived an analytical
bit-error-rate (BER) expression based on spatio-temporal Bussgang decompostion
in matrix form, and mismatched decoding capacity via Generalized Mutual
Information (GMI) is obtained under PA nonlinearity for different hybrid
Massive MIMO architectures. Analytical results show that the nonlinear
distortion significantly affects the system performance, and DPD can reduce
these effects to some extend. Finally, obtained analytical BER expression is
verified via numerical results.
