Analysis of Scattering in Physically Nonstationary Mobile Radio Channels

The results of propagation measurements in an outdoor urban environment using a recently developed 3-D high-resolution channel sounder are analysed. Measurements are performed at a fixed position as well as along a trajectory to characterise the angular dispersion in both azimuth and elevation. A clustering algorithm is used to separate and group the estimated multipath components. The rms cluster angular spread in both elevation and azimuth of the different clusters is analysed over space and time and related to its physical scattering sources.
