Energy efficiency optimisation of large-scale multiple-input-multiple-output system with transmit antenna selection.

The rapid development of wireless communication comes at the cost of dramatically increasing energy consumption, which makes the optimisation of energy efficiency (EE) extremely important. In this study, the authors focus on maximising EE of large-scale multiple-input-multiple-output system by optimising the transmit power and the number of selected base station antennas. First, the EE optimisatio...
