OFDM-IDMA based downlink transmission scheme for femtocell networks. To avoid the
cross-tier interference, we assign the femto users and marco users into different subcarrier …

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 …

In this paper we have analyzed the performance of OFDM_IDMA system by using random
interleaver and Femtocell network. We give detailed system model and the transceiver …

The paper proposes a scheme to minimize the co-tier and cross-tier interference by properly
allocating the sub-channels and power among the femtocell users (FUs) in an OFDMA …

Recently, Studies show that to date the demand for mobile high data rate occurs mainly in
buildings. Moreover based on these studies sixty percentages of voice calls and ninety …

The interference problem is a bottleneck of femtocell development as more and more
femtocells are deployed. This paper considers interference from macro-cell as well as …

Femtocell networks based on cognitive radio can extend indoor capacity by accessing
unused TV or macrocell spectrum bands. In this cognitive femtocell network (CFN), it is a …

Wireless technology plays a dominant role in today's tremendous demand for mobile user
communication. Therefore, improving its ability to provide higher data rates and better …
