Multiband cooperative networking is being recognized as a new enabling scheme to provide
superior user experience and greatly scale up system capacity for 5G cellular networks. This …

Femtocell architecture involves the use of two separate layers-the macrocell and femtocell
layers. In this architecture, the former is the conventional cellular network, whereas the latter …

The coexistence of heterogeneous networks within the same spectrum for enhancing the
spectrum efficiency has attracted large interest lately in the research community …

Intercell interference is the main issue limiting the capacity of modern orthogonal frequency‐
division multiple access based cellular networks. Recently, extensive research work has …

This paper proposes a new population-based heuristic algorithm called Phasmatodea (stick
insect) Population Evolution (PPE) algorithm. The implementation of the algorithm is …

We propose a blind interference alignment scheme for partially connected cellular networks.
The scheme cancels both intracell and intercell interference by relying on receivers with one …

Femtocells are shown highly effective on improving network coverage and capacity by
bringing base stations closer to mobile users. In this paper, we investigate the problem of …

Interference Alignment (IA) has been considered a promising technique for spectral
coexistence of different wireless systems in an underlay cognitive mode. Furthermore …

In this paper, we analyze the non-cooperative power control algorithm based on game
theory in the two-tier femtocell networks, and find that the outcome of the game in a Nash …

We conceive an interference mitigation scheme, for twin-layer networks for protecting the
macrocell-users, from the interference imposed by the femtocells as well as for mitigating the …
