Abstract
It is essential to have deep understanding of the mobile radio channel in particular for radio communication modeling and advanced technology system design. In his paper we employ the recently proposed Eccentro-Scattering physical channel model to derive the probability density functions (pdf) of Angle of Arrival (AOA) of the multipaths at Base Station (BS) from uniformly distributed scatterers for picocell, microcell, and macrocell environments. The Eccentro-Scattering model is easily employed to model any cellular environment with appropriate choice of few model parameters. This provides a unified approach to model all cellular environments that remained absent, so far. The derived formulas for the pdf of AOA of the multipaths at BS can be used further in performance assessment for smart antennas.
