摘要：
In this paper, considering the block fading channels, we utilize a method of requesting expectation to describe this kind of channel. And power control for energy-efficient communication is studied. We are aiming at achieving the energy efficiency maximization for the femtocell network. First, we set up the mathematical model according to the optimization of energy efficiency. Then, the original objective function is transformed into the object function we always study by requesting expectation. Next, the object function is solved by Lagrangian method and figures are plotted to illustrate how to select the optimal power qualitatively. Last, the numerical results illustrate power control algorithm we proposed is effective.
