Abstract
The effects of the presence of the user on
MIMO performance for wireless communications systems is
investigated through measurements in a reverberation
chamber. Measured results have demonstrated that despite a
decrement on the envelope correlation coefficient, a
degradation of both diversity gain and MIMO capacity are
expected when the user is present. While the validity of the
correlation coefficients for predicting MIMO performance is
limited in the presence of the user, the effects have also been
found to be strongly dependent upon frequency, antenna
topology and user characteristics It has been demonstrated that
the power absorbed in the user plays a more important role for
MIMO capacity than the change on the correlation coefficients
due to the user’s presence.
