OFDMA has been selected as the multiple access scheme for state-of-the-art wireless
communication systems. Efficient resource allocation in OFDMA wireless networks is …

A fundamental choice in femtocell deployments is the set of users which are allowed to
access each femtocell. Closed access restricts the set to specifically registered users, while …

We investigate the impact of co-channel deployment of femtocells on the existing macro-
cellular systems considering the techniques to resolve the laud neighbor problem. There are …

WiMAX femtocell is developed to expand cell coverage, increase system capacity and offer
various multimedia services with high throughput in indoor environments. However, several …

The Physical Cell Identity (PCI) is used to identify femtocell in LTE femtocell as the physical
layer identity. Due to the fact that a) the PCIs are normally allocated without planning; and b) …

Femtocells are a promising solution for the provision of high indoor coverage and capacity.
Furthermore, OFDMA-based femtocells have proven to be highly versatile when dealing with …

Femtocell is a solution to increase the system capacity and coverage to meet the high
demand of the next generation of services on broadband wireless access. However, the …

Dense deployment of femtocells in mobile wireless networks can significantly increase the
amount of handover initiations. This paper analyzes new approach to elimination of …

It is envisioned that the ability to provide peak data rates of 1 Gbps in nomadic environments
will be instrumental to the commercial success of 4th generation mobile communication …

To expand private femto-WLANs into public femto-WLANs, we present an integrated system
of cognitive radio and femto-WLANs, cognitive femto-WLANs, which aims at meeting the …
