Analysis of Radio Propagation in Co- and Cross-Polarization in Urban Environment

Abstract

The behaviour of radio propagation in co- and cross-polarization in urban environment is studied with the aid of both ray tracing simulation and MIMO measurements. A ray tracing (RT) model including diffuse scattering has been adopted, therefore allowing the tuning of the RT model and the analysis of the role of diffuse scattering in cross-polarization propagation. A high degree of cross-polarization coupling is observed, especially in NLOS cases, confirming the feasibility of efficient and compact MIMO schemes adopting dual polarized antennas.
