In this paper, a deterministic equivalent of ergodic sum rate and an
algorithm for evaluating the capacity-achieving input covariance matrices for
the uplink large-scale multiple-input multiple-output (MIMO) antenna channels
are proposed. We consider a large-scale MIMO system consisting of multiple
users and one base station with several distributed antenna sets. Each link
between a user and an antenna set forms a two-sided spatially correlated MIMO
channel with line-of-sight (LOS) components. Our derivations are based on novel
techniques from large dimensional random matrix theory (RMT) under the
assumption that the numbers of antennas at the terminals approach to infinity
with a fixed ratio. The deterministic equivalent results (the deterministic
equivalent of ergodic sum rate and the capacity-achieving input covariance
matrices) are easy to compute and shown to be accurate for realistic system
dimensions. In addition, they are shown to be invariant to several types of
fading distribution.
