The global bandwidth shortage in the wireless communication sector has motivated the
study and exploration of wireless access technology known as massive Multiple-Input …

Massive MIMO (multiple-input multiple-output) is no longer a “wild” or “promising” concept
for future cellular networks—in 2018 it became a reality. Base stations (BSs) with 64 fully …

In intelligent reflecting surface (IRS) assisted communication systems, the acquisition of
channel state information is a crucial impediment for achieving the beamforming gain of IRS …

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

The adoption of a reconfigurable intelligent surface (RIS) for downlink multi-user
communication from a multi-antenna base station is investigated in this paper. We develop …

The energy efficiency (EE) of femtocells is always limited by the surrounding radio
environments in heterogeneous networks (HetNets), such as walls and obstacles. In this …

Massive multiple-input multiple-output (MIMO) is one of the most promising technologies for
the next generation of wireless communication networks because it has the potential to …

This paper investigates the impact of residual transceiver hardware impairments (RTHIs) on
cooperative non-orthogonal multiple access (NOMA) networks, where generic fading …

Non-orthogonal multiple access (NOMA) and ambient backscatter communication have
been envisioned as two promising technologies for the Internet-of-things due to their high …

In this paper, we consider multiple-input-multiple-output detection using deep neural
networks. We introduce two different deep architectures: a standard fully connected multi …
