Multiuser hybrid analog/digital beamforming for relatively large-scale antenna arrays

open access: yes, 2013
Power consumption and costs of the analog front-end (AFE) chains are often not negligible for large-scale antenna array systems. A low-complexity hardware architecture is to use a number of AFE chains that is less than the number of the antennas ...
