Abstract -- In this paper we present a new up-
per bound on the mutual information of MIMO sys-
tems. By characterizing the fundamental communica-
tion modes between two physical regions, we develop
an intrinsic capacity which is independent of antenna
array geometries and array signal processing, and de-
pends only on the size of the regions and the statistics
of the scattering environment.
Multiple-Input Multiple-Output (MIMO) communications
systems using multi-antenna arrays simultaneously during
transmission and reception have generated significant interest
in recent years. Theoretical work of [1] showed the poten-
tial for significant capacity increases in wireless channels via
