The energy spectral efficiency maximization (ESEM) problem of a multi-user, multi-relay,
multi-cell system is considered, where all the network nodes are equipped with multi …

Spatial Interference alignment (IA) is a promising scheme to efficiently mitigate interference
and to enhance the capacity of a wireless communication network. In this paper, the …

In this paper, we propose an interference alignment and cancelation (IAC) scheme for the
uplink of heterogeneous networks (HetNets). Due to the random deployment of small cells …

Cellular communication provides an efficient, flexible, long-lived, and reliable
communication technology for smart grids to improve the automated analysis, demand …

Cellular networks are of particular interest when communication takes place. The main
barrier of employing cellular networks to reach broad access everywhere is interference …

This thesis focuses on the energy efficiency (EE) of relay-aided cellular networks, which is
motivated by the ever-increasing need to support higher and higher data rates, while …

In this investigation, a new idea to generalize the downlink interference alignment scheme
for cellular networks is proposed. According to the simulation results, it can be revealed that …

The demand for data-intensive services is on the rise. In order to meet the demands,
communication systems must increase their spectral efficiency (ie, bits/s/Hz/Area). The more …
