Analysis of radio propagation in co- and cross-polarization in urban environment

The behaviour of radio propagation in co- and crosspolarization 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 crosspolarization coupling is observed, especially in NLOS cases, confirming the feasibility of efficient and compact MIMO schemes adopting dual polarized antennas.
