Variation of measured indoor MIMO capacity with receive direction and position at 5.2 GHz

Abstract

Using a directional receive (RX) antenna array the channel capacity of an 8×8 multiple-input multiple-output (MIMO) system in an office scenario at 5.2 GHz for different RX directions and positions is measured. The average MIMO capacity can be related to dominant-wave propagation. However, when path-loss is normalised out, MIMO capacity is nearly independent of RX direction and position.
