Reduction of multipath effect through a critical scattering zone in microcell environments
In this work, we investigate a critical region (CR) in microcell elliptical environments, an area between the mobile and the base station (BS) containing multipaths whose angles and times of arrival possess the acceptable angle and delay spreads of the channel. The focus of the paper is to estimate the theoretical rates of multipath reduction expected from the CR. These rates illustrate the convenience of adjusting or not the antenna's beamwidth (aperture) according to the angle spread. Also, to confirm the model's results; the angle and time of arrival statistics deduced from the elliptical model are validated through simulation. Results closely agree with theoretical values expected from the model.
