Femtocell networks, consisting of a conventional macro cellular deployment and overlaying
femtocells, forming a hierarchical cell structure, constitute an attractive solution to improving …

Femtocells that use co-channel allocation with macrocells can considerably increase
wireless coverage and system capacity, especially for indoor and cell-edge users. However …

Femtocells have been considered as a promising technology to provide better indoor
coverage and spatial reuse gains. However, the co-channel deployment of macrocells and …

One of the effective techniques of improving the coverage and enhancing the capacity and

With the introduction of femtocells, cellular networks are moving from the conventional
centralized network architecture to a distributed one, where each network cell should make …

Femtocell is one of promising key technologies to increase the efficiency and coverage of
next generation broadband wireless networks. However, there exists interference problem …

The deployment of femtocells is uncoordinated and opportunistic, especially in urban
environment where a large number of femtocells are overlapped. Therefore, it is likely that …

Small cells such as femtocells overlaying the macrocells can enhance the coverage and
capacity of cellular wireless networks and increase the spectrum efficiency by reusing the …

Femtocells have a strong potential for increasing the efficiency and coverage of next-
generation broadband wireless networks. In this paper, a co-channel framework for the …

In this paper, we propose a joint subchannel and power allocation algorithm for the downlink
of an orthogonal frequency-division multiple access (OFDMA) mixed femtocell/macrocell …
