- Reduction of multipath effect through a critical scattering zone in microcell environments C. A. López Miranda D. H. Covarrubias Rosales Física, Astronomía y Matemáticas microcell critical region Multipath effect antenna aperture statistical analysis 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 thepaper is to estimate the theoretical rates of multipath reduction expected from the CR. These rates illustrate the convenience of adjusting ornot the antennas beamwidth (aperture) according to the angle spread. Also, to confirm the models results; the angle and time of arrivalstatistics deduced from the elliptical model are validated through simulation. Results closely agree with theoretical values expected from themodel. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064202 https://www.redalyc.org/journal/570/57064202/ https://www.redalyc.org/journal/570/57064202/html/ https://www.redalyc.org/journal/570/57064202/57064202.epub https://www.redalyc.org/journal/570/57064202/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
