Polarization behaviour in urban macrocell environments at 2.2 GHz

Abstract

This paper investigates the polarization behaviour of the propagation channel in urban macrocell environments at 2 GHz. The study is based on a dual polarized single-input multiple-output (SIMO) measurement campaign. The beamforming algorithm which computes the direction of arrivals (DoA) is explained. Two examples of spatio- temporal results representative of the street guided propagation and diffraction over rooftop mechanisms, are analysed. Thereafter, the study focuses on the polarization analysis. The average polarization matrix is computed and compared with previously published results. The polarization dependency with the physical propagation parameters is also investigated. (6 pages)
