碩士 === 國立交通大學 === 電信工程研究所 === 103 === In this thesis, we consider the problem of deciding transmit RF chain configuration aimed to maximize the energy efficiency under the total power constraint in massive MIMO systems. The RF chain configuration can be decided by applying some antenna selection methods. Considering the trade-off between the performance and complexity, we propose a norm-and-correlation-based selection algorithm with low complexity for energy efficiency maximization. The proposed selection algorithm can be applied to decide the RF chain configuration in the massive multiuser MIMO (MU-MIMO) systems as well. Finally, computer simulation results show that the proposed selection algorithm can achieve comparable energy efficiency to conventional antenna selection algorithms in massive MIMO systems.
