A novel interference avoidance scheme for femtocell

Femtocell is one of the most important parts in the future cellular system such as LTE. But the interference problem would be very serious because femtocell works on the same frequency resource as macro-cell system. Considering the femtocell would induce interference between neighbor femtocells and macro-cell users which is very complicated, we proposed a novel scheme for femtocell to avoid any potential interference adaptively. The simulation shows that the proposed scheme could decrease the interference and increase the capacity.
