Popis: This paper presents the derivation of the probability density function (PDF) of angle of arrival (AoA) of multipaths at base station (BS) and mobile station (MS) while directional antennas are used at both ends of the communication link. A macrocell environment is modeled by assuming uniform and Gaussian distribution of scatterers around MS. Closed form expressions for PDF of AoA at BS and MS are obtained as a result of using directional antennas at both ends of the link. The behavior of the PDF of AoA at BS and MS is observed and plotted by changing the separation between BS and MS and in case of Gaussian scatter density the effect of changing the standard deviation is shown on the PDF of AoA at BS and MS.
