Future wireless systems are envisioned to create an endogenously holography-capable,
intelligent, and programmable radio propagation environment, that will offer unprecedented …

Data-driven machine learning (ML) is promoted as one potential technology to be used in
next-generation wireless systems. This led to a large body of research work that applies ML …

Holographic MIMO refers to a (possibly large) array with a large number of individually
controlled and densely deployed antennas. The objective of this paper is to provide further …

In most multiple-input multiple-output (MIMO) communication systems, antennas are spaced
at least half a wavelength apart to reduce mutual coupling. In this configuration, the …

We investigate the benefits of mutual coupling effects between the passive elements of
intelligent reconfigurable surfaces (IRSs) on maximizing the achievable rate of downlink …

We devise an end-to-end (E2E) communication channel model that describes the
performance of reconfigurable intelligent surface (RIS)-assisted MIMO wireless links. The …

As the backbone of the fifth-generation (5G) cellular network, massive multiple-input multiple-
output (MIMO) encounters a significant challenge in practical applications: how to deploy a …

By deploying a large number of antennas with sub-half-wavelength spacing in a compact
space, dense array systems (DASs) can fully unleash the multiplexing-and-diversity gains of …

Super-wideband (SWB) antennas have emerged as a promising technology for next-
generation wireless communication systems due to their ability to transmit and receive …

Massive MIMO systems have received a great deal of attention as a means to improve both
spectral efficiency (SE) and energy efficiency (EE) of wireless networks. While applying …
