Summary:
Spatial processing techniques such as Adaptive Array Antenna (AAA) and Multi-InputMulti-Output (MIMO) have been focused for use in 3rd and 4th generation mobile cellular systems. In order to accurately estimate the performance of these spatial processing techniques in wide-band 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 in order to evaluate spatial processing techniques such as MIMO and AAA, the modelling of arrival angular profile at the base station (BS) is required. In previous works, we proposed an empirical arrival angular profile model at BS in macro cells (Macro-cell arrival angular profile model) where the BS height is higher than the average building height in its coverage area [1],[2]. However, this macro-cell model is invalid for micro cells where BS height is lower than the average building height in its coverage area. In this paper, we measure the arrival angular profiles at the BS in micro cells and clarify the characteristics of the arrival angular profile.
