Polarization Properties of Specular and Dense Multipath Components in a Large Industrial Hall
IEEE Transactions on Antennas and Propagation, 2015Co-Authors: Davy P. Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, Martine Lienard, Viet-chi Tran, Luc MartensAbstract:This paper presents a comprehensive analysis of the polarization characteristics of specular and dense multipath components (SMC and DMC) in a large Industrial Hall based on frequency-domain channel sounding experiments at 1.3 GHz with 22-MHz bandwidth. Twenty-nine positions were measured under line-of-sight (LOS) and obstructed LOS (OLOS) scenarios. The RiMAX maximum-likelihood estimator is used to extract the full-polarimetric SMC and DMC from the measurement data by taking into account the polarimetric radiating patterns of the dual-polarized antennas. Cross-polar discrimination (XPD) and copolar ratio (CPR) values are presented from the measured and de-embedded channels, as well as the polarimetric delay and angular spread distributions. Strong de-embedded SMC depolarization is obtained for the horizontal polarization in OLOS scenarios. Additionally, DMC depolarization is observed to be weaker than previously reported for indoor environments but constant across LOS/OLOS, polarization, and distance. The results also show that the copolar (cross-polar) DMC power to total channel power ratio is equal to 15% (40%) for LOS and 40% (60%) for OLOS and that this ratio does not correlate significantly with transmitter-receiver distance. Finally, the validity of the room electromagnetics theory was confirmed for transmitter-receiver distances larger than 15 m with no significant difference between polarized subchannels.

Polarization properties of specular and dense multipath components in a large Industrial Hall
2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014Co-Authors: Davy P. Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, Brecht Hanssens, Martine Lienard, Luc MartensAbstract:This paper presents an analysis of the polarization characteristics of specular and dense multipath components (SMC & DMC) in a large Industrial Hall based on frequency-domain channel sounding experiments at 1.3 GHz with 22 MHz bandwidth. The RiMAX maximum-likelihood estimator is used to extract the full polarimetric SMC and DMC from the measurement data by taking into account the polarimetric radiating patterns of the dual-polarized antennas. Cross-polar discrimination (XPD) values are presented for the measured channels and for the SMC and DMC separately.
