Statistical characterization of the indoor MIMO channel based on LOS/NLOS measurements

Measurements taken at the campus of Brigham Young University (BYU) are used to investigate the statistical properties of the indoor MIMO channel. The Rician K parameter is estimated along a path in both LOS and NLOS. These values are related to the received power and the spatial spectrum calculated using the conventional beamformer. Furthermore, statistical tests are applied to investigate if the data belongs to a multivariate normal distribution. It is found that the univariate statistics can be approximated by a complex normal distribution but only small MIMO systems may be approximated as multivariate normally distributed.
