Abstract :
The paper investigates the beamforming (BF) performance of large, potentially unconstrained in size antenna arrays when equipped with arbitrarily many elements. A realistic BF criterion namely the average BF gain is revisited and employed to understand the BF performance of large-scale antennas above a user clutter. Simulation results show diminishing average BF gain returns as the number of antennas increases in low angle spread outdoor channels.
