MIMO channel capacity measurements using the VT-STAR architecture

The Virginia Tech Space-Time Advanced Radio (VT-STAR) has been used to collect and process narrowband multiple-input multiple-output (MIMO) channel measurements in a non line-of-sight (NLOS) indoor environment. Following the description of the radio architecture we report here initial representative results of the capacity measured in our indoor laboratory settings. As part of the validation process, the effect of pattern distortion associated with the orientation of the antenna arrays is discussed. We compare the theoretical capacity results of [2] with the measured capacities obtained by a MIMO configuration, receive diversity (with single transmit antenna), transmit diversity (with single receive antenna) and a single-input single output (SISO) channel only.
