In this paper, we investigate the energy efficiency (EE) of massive multiple-input multiple-output (MIMO) systems with linear maximum ratio combining (MRC) and zero-forcing (ZF) receivers. To be practical, the baseband power consumption with algorithm computational complexity (ACC) is taken into account. Utilizing this model, we maximize the global optimal number of receiver antenna and sum rate with optimal EE by fixed the number of users for different receivers, respectively. In parallel, the low complexity iterative algorithm is proposed to reap the optimal values. Simulation results indicate that the EE improves with the number of users for the two receivers.
