| Abstract(in English) | Spatial processing techniques such as Adaptive Array Antenna (AAA) and Multi-Input-Multi-Output (MIMO) have been the focus for realizing 4th and 5th generation mobile cellular systems. In order to accurately estimate the performance of these spatial processing techniques for high speed broadband mobile communications, we need a time-spatial path model that allows the characteristics of the delay profile and those of the spatial arrival angular profile for travelling waves to be simulated at the same time. Especially for spatial processing techniques such as Massive MIMO, not only the azimuth arrival angular profile but also elevation arrival angular profile must be modelled. While many studies on the elevation arrival angular characteristics at high base station have been carried out, few have examined in adequate depth the elevation arrival angular characteristics at low base station. Thus, there is need for an elevation arrival angular profile model at low base station that can take city structures into consideration in order to fully evaluate spatial processing techniques such as Massive MIMO in various outdoor propagation environments. In this paper, we measure and analyze the elevation arrival angular characteristics at low base station in urban area. |
