【 摘 要 】

In this paper, we discuss the energy efficiency (EE) of co-located massive multiple-input-multiple-output (MIMO) system. After analysis, we obtain the EE expressions of the idealistic and the realistic power consumption models, respectively. Through the numerical results, we detail relationship between EE and the maximum transmit power, and the relationship between EE and the number of the base station (BS).
