This paper studies transmit optimization for a multiple-input multiple-output (MIMO) femtocell
that coexists with a macrocell by concurrently accessing the same frequency bands in an …

Recently the use of modern cellular networks has drastically changed with the emerging
Long Term Evolution Advanced (LTE-A) technology. Homogeneous networks which were …

The increasing demands of various high data rate wireless applications have been seen in
the recent years and it will continue in the future. To fulfill these demands, the limited existing …

In order to cancel the heavy interference experienced by the femtos from the Macro Mobile
stations (MSs) in uplink owing to the bandwidth used by the macro MSs is reused by the …

This paper considers resource allocation and transmission optimization for femtocell
networks, where the orthogonal frequency division multiple access (OFDMA) strategy is …

Today's wireless communication systems are driven by the need for ubiquitous wireless
services at high capacity. This has led to the search for a promising solution to provide better …

In the last decade, cellular networks have been characterized by an ever-growing user data
demand that pushed for more and more network capacity to be satisfied. This caused …

The concept of femtocell aims to combine fixed-line broadband access with mobile
telephony using low cost and power third and fourth generation base stations in the …

Femtocell techniques can address the poor in‐building coverage problem and increase the
network capacity cost‐efficiently. Until now, some Wireless Service Providers (WSPs) have …
