Increasing energy efficiency through maximizing channel capacity with a minimum power allocation in the Femtocell network

Femtocell networks are a very promising solution for increasing the system capacity via making the transceiver and transmitter close to each other. This makes links with higher qualities. The spectrum dedicated to the femtocell network is mainly from the spectrum licensed given to macrocell. This paper investigates the maximum of the energy efficiency in Downlink connections of the femtocell networks over a fading environment. To increase the energy efficiency in the femtocell network, optimizing capacity and power are studied at the same time. The power allocation limits and channel capacity increase are considered simultaneously. In this article, it is concluded that simultaneous optimization of the channel capacity increase and power allocation limits leads to an energy efficiency increase in these networks.
