Abstract
Una unidad de abonado de radio (102) tiene una aparato receptor en diversidad (106) que incluye una primera antena (114) y una segunda antena(116). Una primera representación (158) y una segunda representación (160) de una senal de radiofrecuencia compuesta se recibe desde la primera antena (114)y la segunda antena (1169), respectivamente. La senal de radiofrecuencia compuesta incluye una senal de radiofrecuencia deseada (156)y senales deinterferencia (166). La senal de radiofrecuencia deseada (156) incluye por lo menos una senal piloto codificada (Ec). Una relación (Ec/Io) de la por lo menosuna senal piloto codificada (156) incluye por lo menos una senal piloto codificada (Ec). Una relación (Ec/Io) (142) de la por lo menos una senalpiloto codificada (Ec) a un cálculo de la senal de radiofrecuencia compuesta se determina en respuesta a por lo menos la primera representación (158) de lasenal de radiofrecuencia compuesta y la segunda representación (160) de lasenal de radiofrecuencia compuesta. Un estado seleccionado de la primera antena(114) y la segunda antena (116) se controla en respuesta a por lo menos una relación (Ec/Io) (142) y una indicación de intensidad de senal recibidaintegrada (RSSI) de la senal de radiofrecuencia compuesta.
