As the growth of wireless communications is accompanied by increased energy consumption, energy-efficient communication is becoming imperative. This paper will discuss the energy efficiency of MIMO systems with antenna selection. The optimal method for the maximization of energy efficiency is exhaustive search. To address the problem, an iterative algorithm which includes the transmit antenna selection...
The design of wireless communication systems under holistic power models has been being a hot topic in green communications. In this letter, we shall investigate the antenna selection in multi-stream MIMO with circuit power consumption. The difficulty lies in the fact that the optimal active antennas can only be selected by exhaustive search. To reduce the complexity, two iterative properties of MIMO...
