Millimetre wave (mm-Wave) bands and sub-6 GHz are key technologies in solving the
spectrum critical situation in the fifth generation (5G) wireless networks in achieving high …

Cognitive femtocell has emerged as one of the promising ways to solve the indoor coverage
and spectrum shortage problems in cellular networks. However, it is a challenge to motivate …

We address the femtocell clustering together with the resource allocation in macro-femtocell
networks. The clustering schemes allow the implementation of distributed approaches that …

In this paper, we address the problem of resource allocation under high user density
environment in OFDMA macro-femotcell networks. In the literature, several solutions have …

In this paper, we consider the problem of resource allocation in non-dense macrocell–
femtocell networks. We build a comprehensive realistic framework that overcomes the …

In this paper, we tackle the problem of resource management in macro-femtocell networks.
Dense deployment of femtocells imposes several challenges for a cluster-based resource …

Femtocells have been deployed to enhance indoor coverage, improve the system capacity
of cellular networks, and increase the spectrum efficiency by means of full subcarrier reuse …

Visible light communication (VLC) is the branch of optical wireless communications that
uses light‐emitting diodes for the dual purpose of illumination and very‐high‐speed data …

This paper presents an approach of a Matlab/Simulink-based model for Hybrid M-QAM/L-
FSK (4/16 HQFM) modulation scheme with a non-coherent detection of 4-ary FSK …

With the next generation of mobile networks closing in, its main characteristics have already
been proposed and adapted. Ultra-dense heterogeneous networks seem to be one of the …
