Experimental Multipath Component Results from MIMO Measurements in a Microcell Urban Environment

This paper presents results on the parameters of multipath components extracted from wideband measured MIMO channel matrices. Experimental data were collected with wideband channel sounding measurements at 5.2 GHz in a microcell urban environment, under line of sight propagation conditions. The double directional and propagation delay parameter values of the dominant multipaths were estimated using the multidimensional parameter estimation algorithm. The results presented provide information in the context of parametric MIMO channel characterization and refer to the number of identified waves, and focus on the path weights characteristics. Additionally, the extracted multipath estimates are used to synthesize MIMO matrices that are compared to the directly measured data.
