Abstract :
[en] This paper aims at a realistic evaluation of Rayleighproduct
multiple-input multiple-output (MIMO) systems. Specifically,
by considering the residual transceiver hardware impairments
into account, we derive the ergodic channel capacity of a
MIMO system with optimal receivers in the case of insufficient
scattering. Actually, motivated by the increasing interest for
massive MIMO systems, we investigate the impact of transceiver
hardware imperfections in systems with both finite (conventional)
and large number of antennas under rank deficient channel
matrix conditions by varying the severity of hardware quality.
Among the interesting outcomes, we emphasize that the residual
hardware transceiver impairments result to a saturation of the
ergodic channel capacity within the high signal-to-noise ratio
(SNR) regime. Furthermore, we observe that the higher the
“richness” of the scattering environment, the higher the ergodic
channel capacity till it gets saturated.
