Abstract

Se describe un proceso de seleccion de diversidad para una terminal inalámbrica que tiene dos antenas, el cual prueba la recepcion tanto en la antena principal como en una antena de diversidad, durante el periodo cuando la terminal se encuntra transmitiendo y prueba la recepcion de un canal diferente (por ejemplo, para una conmutacion asistida movil) durante un periodo libre cuando la terminal no se encuentra transmitiendo o recibiendo datos. La antena con la intensidad de señal mayor se selecciona para la siguiente estructura. De esta manera, tanto las mediciones de conmutacion asistida movil como de diversidad pueden hacerse con un solo receptor.
