Maximum Energy Efficiency of Three Precoding Methods for Massive MIMO Technique in Wireless Communication System

Nowadays, Energy Efficiency (EE) has turned into a buzzword for 5G. Consequently, Massive MIMO (MMIMO) technologies have attained a great attention for Multi-User Communication scenario. In this paper, the Minimum Mean Square Error (MMSE), the Maximum Ratio Transmission (MRT) and the Zero Forcing (ZF) precoding methods are analyzed for MMIMO technique from an EE perspective. The results show the optimization of EE against the amount of clients, amount of assigned base stations as well as launch input power in the system respectively.
