abstract = {Distributed MIMO (D‐MIMO) systems are expected to play a key role in deployments for
future mobile communications. Together with massive MIMO technology, D‐MIMO aims to
maximize the spectral efficiency and data rate in mobile networks. This paper proposes a deep study
on the spectral efficiency of D‐MIMO systems for essential channel parameters, such as the channel
power balance or the correlation between propagation channels. For that purpose, several
propagation channels were acquired in both anechoic and reverberation chambers and were
emulated using channel simulators. In addition, several frequency bands were studied, both the
sub–6 GHz band and mmWave band. The results of this study revealed the high influence of
channel correlation and power balance on the physical channel performance. Low‐correlated and
high‐power balance propagation channels show better performances than high correlated and
power unbalance channels in terms of spectral efficiency. Given these results, it will be fundamental
to take into account the spectral efficiency of D‐MIMO systems when designing criteria to establish
multi‐connectivity in future mobile network deployments.},
