Energy Efficiency Analysis of a single-cell Massive MIMO Systems

Abstract

We analyze EE for the multi-user massive MIMO systems in the single-cell. Primarily the circuit model of power consumption is elaborated, which describes the process of influence the circuit power consumption by the antenna number and user number in detail.  Then it demonstrates the closed-form expression of EE, which depicts the relationship between the influence factors and obtained downlink EE.  The factors include the number of users, the transmission power and the number of BS antennas. The simulation provides information where it is shown that with medium numbers of antennas and users optimal EE is acquired.
