A novel base station antenna (BSA) configuration is presented to mitigate degrading
physical antenna effects in massive multiple-input multiple-output (MIMO) systems, while …

In this paper, we study the cooperative beamforming schemes for multi-cell multi-user full-
dimensional (FD) massive multiple-input multiple-out (MIMO) networks. In the considered …

Abstract The Large Scale Multiple-input-multiple-output (MIMO) system, also called Massive
MIMO in past researches, are considering the azimuth angle only. However, in a 3D …

In this paper, we investigate the omnidirectional precoding for three dimensional (3D)
massive multi-input multi-output (MIMO) with uniform planar arrays (UPAs). The …

In this paper, we consider the design of two-stage beamformers for the downlink of multi-
user frequency-division-duplexing (FDD) massive multiple-input multiple-output (MIMO) …

In this work, we propose a beam selection scheme that exploits the geometric sparsity of the
multi-user (MU) massive multiple input and multiple output (MIMO) channel, using its …

Recently massive multi-input multi-output (MIMO) techniques have attracted growing
research interest. However, most existing works assume centralized control, which may …

Multiuser beamforming is considered for partially-connected millimeter wave massive MIMO
systems. Based on perfect channel state information (CSI), a low-complexity hybrid …

This paper proposes a unified transmission strategy for multiuser time division duplex
(TDD)/frequency division duplex (FDD) massive multiple-input-multiple-output (MIMO) …

This paper designs a novel hybrid (a mixture of analog and digital) beamforming and
examines the relation between the hybrid and digital beamformings for downlink multiuser …
