Design of Millimeter Wave Hybrid Beamforming Systems

open access: yes2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014
Millimeter wave (mmWave) signals experience a significant path-loss in free space. To overcome this weakness, a large number of antennas are needed to obtain a high beamforming gain.

Adaptive optical processing for wideband hybrid beamforming

open access: yesIEEE Transactions on Communications, 2019
Multiuser centralized radio access networks (C-RANs) need to adapt to time-varying radio environments, and adaptation is advantageously split between remote antenna units (RAUs) and centralized baseband units (BBUs) to minimize the required fronthaul ...

Lattice-Based mmWave Hybrid Beamforming [PDF]

open access: yesIEEE Transactions on Communications, 2021
Conventional hybrid precoding and combining based transceivers require a large number of high-resolution radio frequency (RF) phase shifters (PSs), which impose prohibitive hardware costs and power consumption. To address the above issue, both partially connected RF PSs and low-resolution PSs have been proposed. However, the performance limits of these

Hybrid Beamforming for Massive MIMO: A Survey [PDF]

open access: yesIEEE Communications Magazine, 2017
Hybrid multiple-antenna transceivers, which combine large-dimensional analog pre/postprocessing with lower-dimensional digital processing, are the most promising approach for reducing the hardware cost and training overhead in massive MIMO systems. This paper provides a comprehensive survey of the various incarnations of such structures that have been ...
