As a new degree of freedom (DOF), orbital angular momentum (OAM) has the potential of
greatly enhancing the channel capacity of wireless communication systems. However, the …

Due to high bandwidth and small antenna size, millimeter-wave (mmWave) integrated line-
of-sight (LOS) multiple-input-multiple-output (MIMO) systems have attracted much attention …

In the millimeter-wave (mm-Wave) multiuser-multiple-input multiple-output (MU-MIMO)
system, the interferences among different users generally degrade the system performance …

This article investigates the achievable spectral efficiency (SE) of millimeter wave massive
multiple-input multiple-output systems with three different array topologies deployed at the …

In this paper, we investigate the network connectivity of wireless sensor networks with
directional antennas. In particular, we establish a general framework to analyze the network …

We consider the design of a uniform circular array (UCA) system under array misalignment
over line-of-sight (LoS) channels. UCAs have been considered as useful array structures …

In this letter, we consider a uniform circular array (UCA)-based line-of-sight multiple-input-
multiple-output system, where the transmit and receive UCAs are parallel but non-coaxial …

Multiple-input-multiple-output (MIMO) has proved to be a success for the fourth generation
(4G) long term evolution (LTE) and is one of the key technical enablers for evolved mobile …

The capacity of millimeter-wave (mmWave) line-of-sight (LOS) multiple-input multiple-output
(MIMO) channel can be reduced due to the absence of rich scattering. However, the …

Accurate channel parameter estimation is challenging for wideband millimeter-wave
(mmWave) large-scale hybrid arrays, due to beam squint and much fewer radio frequency …
