Interference Mitigation in Femto-Cell Using Power Control Scheme

Muhammad Arif, Sadique Ahmad Bugti, Asad Ali, Atifullah Khan, Saeed Ahmed Magsi


Femto-cell Networks are low-cost, low-range, low-power home base-stations installed at end-user premises like large buildings. However, the low-cost of femto-cells is associated with reusing the frequency used by the macro-cell base-transceiver-station (BTS). This reuse frequency gives rise to interference issue. In this study, we propose a novel power control scheme technique to avoid interference among the macro-cell and micro-cell of a femtocell. The proposed technique not only takes wall penetration into account but also does not degrade uplink and downlink performance. Simulation results show a significant decrease in interference and considerable increase in throughput.
