Massive MIMO in Line-of-Sight Propagation

By calculating the effective max-min SINR (signal-to-interference-plus-noise ratio) and the corresponding power controls explicitly, and selectively dropping a small number of mobiles based on a simple and effective algorithm, we demonstrate that for both downlink and uplink, employing maximum-ratio or zero-forcing linear pre-coding and de-coding, Massive MIMO with max-min power control performs comparably in LoS (Line-of-Sight) and iid (independent and identically distributed) Rayleigh fading propagation environments.
