Abstract

UN SISTEMA DE COMUNICACION CELULAR MOVIL, UNA ESTACION BASE SE CONECTA A UNA RED DE AREA LOCAL (LAN) Y TIENE COMUNICACION SIN CABLE CON UNA PLURALIDAD DE ESTACIONES MOVILES. DESVANECIMIENTO DE MULTICAMINOS SE REDUCE SUSTANCIALMENTE EN EL SISTEMA MEDIANTE LA UTILIZACION DE TECNICAS DE DIVERSIDAD DE ANTENA EN LA ESTACION BASE Y CADA UNA DE LA PLURALIDAD DE ESTACIONES MOVILES. LA COMBINACION DE LA OPERACION INDEPENDIENTE DE DIVERSIDAD DE SELECCION DE ANTENA TANTO EN LA ESTACION BASE COMO EN LA ESTACION MOVIL RESULTA EN LA SELECCION DEL MEJOR CAMINO DE PROPAGACION ENTRE LAS DOS ESTACIONES.
