Abstract

In previous works, they mainly concern on optimizing transmitted antenna to maximize energy efficiency(EE). But the transmitted power optimization is also necessary for the improvement of EE. Because too large or too small transmitted power will lead to the decline of EE. This paper proposes a joint optimal transmitted power and transmitted antenna number iterative algorithm to maximize EE for massive MIMO system. Firstly a good approximation of multi-user interference(MUI) is derived. Then we demonstrate that EE is a concave function of the transmitted power and the transmitted antenna number. So for a given number of transmitted antenna, we can get the optimal transmitted power. An iterative algorithm that can maximize EE is proposed. The monte carlo simulations verify the effectiveness of the proposed algorithm.
