Massive Multiple Input Multiple Output (MIMO) has the potential to satisfy the requirements of the fifth generation (5G) and beyond networks with regard to factors like high data rate, high efficiency, reliability, better performance, and degree of freedom. However, increasing the number of antennas can lead to design challenges such as hardware complexity, higher cost, and large circuit power consumption. In addition to the parameters mentioned above, Energy Efficiency (EE) also needs to be considered a key parameter to analyze the performance of a cellular network. In this paper, Transmit Antenna Selection (TAS) technique based on the normalized power received by the user is proposed for a single-cell multiuser massive MIMO system. The energy efficiency equation is derived by considering both uplink and downlink communication for Zero Forcing (ZF) technique. The power consumption in the Radio Frequency (RF) chain, channel estimation process, and linear processing of the base station are considered for the analysis. The proposed TAS technique improves EE by 5 Mbit/Joule compared to the conventional massive MIMO system for ZF. This study compares Maximal Ratio Transmission (MRT), Minimum Mean Square Error (MMSE), and Zero Forcing based on energy efficiency performance using transmit antenna selection. © 2022 Seventh Sense Research Group®
