Abstract
Cooperative massive MIMO systems have emerged as an attractive solution to meet the demands of the next generation wireless communication systems. Antenna selection at the base stations can significantly reduce the hardware and computational complexities of such systems. In this paper, we propose three sub-optimal antenna subset selection schemes based on the SNR maximization at the scheduled users with zero-forced beamforming transmission at the base stations. Simulation results show that our proposed schemes outperform other schemes with similar computational complexities and even surpass some of the higher computational complexity schemes in a massive MIMO setting.
