Effects of Cross-polarization on Propagation Characteristics of mm-Wave Channel in Metro Carriage

Based on the Shooting and Bouncing Ray Tracing Method / Image Method (SBR / Image method), the influence of cross-polarization on the characteristics of 28 GHz millimeter-wave channels (path loss, delay spread, direction of arrival) is studied. The simulated results of the co-polarization (V-V) are in good agreement with the measured results of the original literature. Furthermore, the influence of cross-polarization on channel characteristics is studied, which provides a theoretical basis for the successful deployment of 5G mobile communication networks.
