After introducing the criteria for their classification, the vectorial model is deeply described. Emphasis is made in the circular, elliptic, and gaussian approximations, taking into account the Doppler effect. Finally, the systems’ behaviour is simulated in different scenarios, validating the corresponding models and evaluating several situations of practical interest for the introduction of intelligent antennas.}, publisher = {URSI 2006, XXI Simposium Nacional de la Unión Científica Internacional de Radio, Oviedo, p. 120-123}, title = {Estudio de modelos para la caracterización del canal de radio en comunicaciones móviles de 2.5G y 3G}, author = {Marante Rizo, Francisco Reinerio and Marante Torres, Reinel and Rodríguez Linares, Ernesto Yudreane and García García, José Ángel}, }
