Interference minimization schemes in OFDMA-based femtocells

Femtocells are deployed to improve the cellular coverage and network capacity in indoor area. Despite their great indoor coverage, the implementation of femtocell by high number of subscribers causes serious interference problem between femto Base Stations (fBSs) and cellular macro Base Stations (mB...
