Angle of Arrival and Time Delay in Urban Radio Links

This thesis, investigates the propagation characteristics in the urban environments by modeling the received signal distribution in the angle-of-arrival (AOA), azimuth, elevation, and time delay (TD) domain for various elevations of the base station (BS) antenna located below and at the level as roof-tops. A novel statistical model is proposed, as a superposition the model that representing an array of Poisson-distributed buildings on the rough terrain, and the waveguide model, which representing a grid of crossings straight streets with buildings aligned along them. Joint distribution of the received signal in the azimuth-elevation and azimuth-time delay domains are derived and analyzed using measurements collected in the built-up areas of Helsinki and the campus of the Aalborg University. Considering the micro-cell conditions, the BS antenna was considered to be on the rooftops level. The distribution of the collected measurements in the 3D domain was accurately predicted using the proposed model. Specifically, the guiding effect in the collected measurements was accurately predicted by taking into account the physical structure of the building topography and the position of the base station antennas with respect to the buildings’ rooftops.
