Abstract :
The channel capacity of an 8 × 8 multiple-input multiple-output (MIMO) system was measured in a rich-scattering office scenario at 5.2 GHz. It was found that there exist remarkable receive positions and directions within a single office, where a strong reduction in MIMO capacity can be observed. Another reduction is due to different transmit array alignment. Investigating the directions-of-departure and direction-of-arrival, it was shown that these effects are related to dominant-wave propagation.
