Photonic Hybrid Precoding for Millimeter Wave RoF Systems
Large propagation path loss and limited scattering of millimeter wave (mmwave) channels create new challenges for physical layer signal processing. Hence, in this article, we propose a photonic hybrid precoding model for mmwave radio-over-fiber systems that overcomes hardware constraints on radio frequency precoding.

Hybrid centralized-distributed precoding in fronthaul-constrained CF-mMIMO systems [PDF]
We investigate a fronthaul-limited cell-free massive multiple-input multiple-output (CF-mMIMO) system and propose a hybrid centralized-distributed precoding strategy that dynamically adapts to varying fronthaul and spectral efficiency (SE) requirements ...

Hybrid Analog and Digital Precoding Design in Multiuser MIMO Systems
In this paper, we proposed the hybrid precoding and hybrid decoding systems of multi-user multi-input multi-output (MU-MIMO) over the millimeter-wave band to improve the system\ue2s spectrum efficiency. Consider that the base station and user equipments (

: Hybrid precoding design is challenging for millimeter-wave (mmWave) massive MIMO. Most prior hybrid precoding schemes are designed to maximize the sum spectral efficiency (SSE), while seldom investigate the bit-error-rate (BER). Therefore, this letter

Hybrid Precoding and Combining Design for Wideband Millimeter Wave Systems
In this thesis, we focus on the wideband millimeter-wave(Mmwave) systems and propose a hybrid precoding and combining design. In this case that large-scale antenna array equipped at both the transmitter and receiver, the conventional fully-digital ...

Hybrid Analog-Digital Precoding Revisited Under Realistic RF Modeling [PDF]
In this letter, we revisit hybrid analog-digital precoding systems with emphasis on the modeling of their radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations.
