This article presents a novel application of the time-gating technique to the field of
propagation channel study. The time-gating technique is well known in the field of antenna measurement
and it is used to eliminate reflected components in outdoor measurements or anechoic chambers. In this
article, we present a new measurement configuration for shielded chambers that allows to configure
different propagation scenarios. In this configuration, the chamber is covered in one part with absorbers and
in the other without absorbers (in order to generate reflected components). Applying the time-gating
technique, we can modify, adjust and tune the reflections that a certain propagation environment has. This
yields a relative control of the propagation environment in both far field and near field regions and allows
to quantify the spectral efficiency and signal correlation that MIMO systems would display operating in
those propagation environments.
