Abstract :
We present measurement results of indoor multiple-input multiple-output (MIMO) multipath wireless channels in the unlicensed national information infrastructure (U-NII) 5.25 GHz band for wireless local area network (WLAN) applications. MIMO channel impulse responses were measured at different locations using co-polarized (copol) and cross-polarized (crosspol) antennas under line-of-sight (LOS) and non-line-of-sight (NLOS) channel conditions in office and cafeteria type environments. Ricean k-factors, correlations, crosspol discriminations (XPD), pathloss (PL) and RMS delay spread (τrms) were computed for different antenna configurations (copol/crosspol) and different channel conditions (LOS/NLOS). Models were developed to characterize the distance dependent variation and the statistical deviations of these parameters.
