In this paper, we implement transmit antenna selection to enhance the energy efficiency of large scale multiple antenna systems. Two easy but effective antenna selection algorithms, Sequential Search Algorithm (SSA) and Binary Search Algorithm (BSA) are proposed to obtain the maximal energy efficiency. In addition, BER performance is determined using non-linear receivers which integrate minimum mean-square error equalization with successive interference cancellation. The simulation results show MMSE-SIC detection technique exhibit 40% better BER performance than ZF-SIC and MRC-SIC.
