On ergodic rates and optimal array geometry in line-of-sight massive MIMO

We investigate the achievable ergodic rate of Massive multi-input-multi-output (MIMO) system in environments with high mobility and line-of-sight (LoS). A 3-dimensional geometric model with uniform rectangular array at the base station (BS) is used for the investigation. We derive a closed form expression for a lower bound on the uplink ergodic rate taking… CONTINUE READING
