AB - Polarization diversity techniques have not received
as much attention as others due to the significant difference
in mean signal level between copolarized and cross-polarized
branches when one polarization is transmitted. However, multiple-
input–multiple-output (MIMO) systems where the multipath
fading is only partially correlated could use polarization diversity
to provide a high diversity gain. Hence there is a need to fully
understand the role of true polarization diversity in such systems.
In this letter, progressive (true) polarization diversity performance
for 3 3 MIMO systems under Rayleigh-fading environments is
evaluated through simulations and measurements. True polarization
diversity was found to be as significant as spatial diversity at
improving diversity gain, and hence MIMO system capacity.
