Query: Modeling the Multipath Cross-Polarization Ratio for Above-6 GHz Radio
  Links   In this paper, we parameterize an excess loss-based multipath component (MPC)
cross-polarization ratio (XPR) model in indoor and outdoor environments for
above-6 GHz frequency bands. The results are based on 28 measurement campaigns
in several frequency bands ranging from 15 to 80 GHz. A conventional XPR model
of an MPC assuming a constant mean value fits our measurements very poorly and
moreover overestimates the depolarization effect. Our measurements revealed a
clear trend that the MPC XPR is inversely proportional to an excess loss in
reference to the free-space path loss. The model is physically sound as a
higher excess loss is attributed to more lossy interactions or to a greater
number of interactions with objects, leading to a greater chance of
depolarization. The measurements furthermore showed that the MPC XPR is not
strongly frequency or environment dependent. In our MPC XPR model, an MPC with
zero-dB excess loss has a mean XPR of 28 dB. The mean XPR decreases half-a-dB
as the excess loss increases by every dB and the standard deviation around the
mean is 6 dB. The model is applicable to existing channel models to reproduce
realistic MPC XPRs for the above 6-GHz radio links.
