| Özet: | Femtocell network is a new technology that uses the advantage of an Internet backbone to
enhance the cellular coverage in residential or small business areas. However, due to the expected
random deployment of the femtocell access point (FAPs), there is a strong probability of interference
among the femtocell nodes and between the femtocells and the macrocell nodes. In this paper, an
interference enhancement is developed and designed for two tiers macro-femtocell networks. An
adaptive power control is calculated based on selecting the minimum interference channel with the
optimized channel gain. In the simulation a number of the FAPs, the distance between the macrocell
and the femtocell and the path loss between the macrocell node and the FAPs are used as design
parameters. The results show a performance enhancement in the interference degradation ratio (DR).
