As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

The emerging massive/large-scale multiple-input multiple-output (LS-MIMO) systems that
rely on very large antenna arrays have become a hot topic of wireless communications …

Imagine a coverage area where each mobile device is communicating with a preferred set of
wireless access points (among many) that are selected based on its needs and cooperate to …

Multiple antenna technologies have attracted much research interest for several decades
and have gradually made their way into mainstream communication systems. Two main …

Imagine a coverage area with many wireless access points that cooperate to jointly serve
the users, instead of creating autonomous cells. Such a cell-free network operation can …

This paper investigates an intelligent reflecting surface (IRS)-aided multi-cell multiple-input
single-output (MISO) network with a set of multi-antenna base stations (BSs) each …

The mobile data traffic has been exponentially growing during the last several decades. This
was enabled by the densification of the network infrastructure in terms of increased cell …

This paper considers a downlink cloud radio access network (C-RAN) in which all the base-
stations (BSs) are connected to a central computing cloud via digital backhaul links with …

This paper presents an overview of the theory and currently known techniques for multi-cell
MIMO (multiple input multiple output) cooperation in wireless networks. In dense networks …

This paper considers a multi-cell multiple antenna system with precoding used at the base
stations for downlink transmission. Channel state information (CSI) is essential for precoding …
