To deal with the increasing demand of high speed data streaming and good quality
voice traffic from mobile users at home, Femtocell Networks are deployed in homes
that enables an indoor mobile user to achieve high speed downloading from the internet
and make good quality voice calls. A femtocell network also provides relief to
an overloaded macrocell network by servicing mobile users at home which without
the femtocell network have to be served by the macrocell. However, like all wireless
networks, femtocell networks suffer from the problem of interference. In this thesis,
a contribution to the existing research on the avoidance of interference in femtocell
networks is presented.
