Abstract

We consider a multiuser MIMO-OFDMA scheme
which exploits multiuser diversity in all dimensions: time, frequency
and space. The main contribution of this paper is the
evaluation and explanation of multiuser MIMO in a real world
scenario, i.e. a large office room, based on measured channels.
We report interesting results of a measurement campaign which
suggest that significant MIMO gains are possible in an indoor
environment even under strong line-of-sight condition as long as
the distance of the users from the base station is larger than a
reverberation distance which only depends on room surface and
material. We show results on the achievable multiuser MIMO
data rates for the given scenario, compare to theoretical limits
and discuss the results in the light of the insights gained from
the measurement campaign. We also introduce restrictions on
the rate distribution between users, i.e. QoS constraints. It is
shown that the theoretical limits can be approximately achieved
provided that the users which compete for the spatial resources
are carefully chosen.
