The impact of angle of arrival distribution on the performance analysis of different antenna array architectures

Abstract

The effects of both azimuth-of-arrival (AOA) and elevation-of-arrival (EOA) on the system performance using different type of antenna array (AA) architectures are investigated. This includes uniform linear array (ULA), uniform circular array (UCA) and uniform rectangular array (URA) configurations. The spatial correlation (SC) of the AA under study for different statistical probability density functions (PDFs) for the azimuth and elevation angles are examined and analysed. The results show that the impact of using different AOA and EOA PDFs on SC is insignificant. The key parameter for system performance is the standard deviation of the underlying PDFs.
