In this paper we present analytical expressions for the angle-of-arrival (AOA) power density function (PDF) and its application in geometrically based channel models for urban environments. In order to evaluate the theoretical clusters PDF in angle domain proposed, we make computer simulations and comparisons with experimental results for wideband channel models, published in the open literature. The comparison with experimental results shows good agreement. The generalized clusters PDF derived in this paper can be used to simulate a power-delay-angle profile and to quantify second order statistics, i.e., angle spread for a given elliptical shape of the cluster.
The simulation approach is an important tool used for the design and implementation of mobile radio systems with an emphasis on the propagation modeling for wireless channel. In this paper. we carried out simulations for three different street positions scenarios o f the receiver, (mobile station). using the Geometrical-Based Single Bounce Elliptical Channel model. as might be appropriate for microcellular applications and mobile-to-mobile communication. From the simulation results we use the parameters time-of-arrival (TOA) and angle-of-arrival (AOA), (delay and angular domain. respectively), to estimate the higher order channel statistics, such as the delay spread (DS) and the angle spread (AS). respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
