The inter-cell interference (ICI) is a major bottleneck that harshly impairs the cell-edge
performance in the cellular networks. In heterogeneous networks (HetNets), time domain …

Cell-free massive multiple-input multiple-output (MIMO) systems consist of geographically-
distributed multi-antenna access points (APs) that form a virtual massive MIMO array. To …

Existing cellular technologies are rapidly coming to their performance limits. This is due not
only to the growth in data traffic and in the number of connected terminals, but also because …

Operators, struggling to continuously add capacity and upgrade their architecture to keep up
with data traffic increase, are turning their attention to denser deployments that improve …

Wireless communication systems have been evolving since the first generation. With the fifth
generation of wireless systems, not only the evolutionary aspect of increased data rates is …

Integrated sensing and communication (ISAC) qualifies mobile radio systems for detecting
and localizing of passive objects by means of radar sensing. Advanced ISAC networks rely …

In this paper, we consider a relative received link power (RRLP)-based coordinated multi-
point (CoMP) joint transmission (JT) in the multi-tier ultra-dense networks (UDN). In this …

Improper Gaussian signaling (IGS) scheme has been recently shown to provide
performance improvements in interference-limited networks as opposed to the conventional …

We consider a multi-cell non-orthogonal multiple access (NOMA) system with coordinated
base stations and investigate its downlink user coordination mode selection and resource …

Cellular broadband Internet of Things (IoT) applications are expected to keep growing year-
by-year, generating demands from high throughput services. Since some of these …
