Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE CONTROL PARA UN RECEPTOR DE FM CON VARIAS ANTENAS, EN EL QUE LA SEÑAL RECIBIDA POR CADA ANTENA SE MEZCLA CON UNA PORTADORA GENERADA EN EL RECEPTOR, Y DE ESTA FORMA LAS SEÑALES MEZCLADAS ORIGINADAS SE ADICIONAN CON LA POSICION DE LA FASE CONTROLABLE EN UNA SEÑAL ACUMULADA, Y LA POSICION DE LA FASE DE LAS SEÑALES MEZCLADAS A ADICIONAR, SON CONTROLADAS RESPECTIVAMENTE EN FUNCION DE LA DIFERENCIA DE FASES, ENTRE LA RESPECTIVA SEÑAL MEZCLADA Y LA SEÑAL ACUMULADA. PARA LA OPTIMIZACION DEL COMPORTAMIENTO DE REGULACION DEL SISTEMA DE CONTROL SE HA PREVISTO, SEGUN LA INVENCION, UN ORGANO DE RETARDO (200, 201) QUE COMPENSA EL RETARDO DE LA SEÑAL ORIGINADO POR MEDIOS DE SELECCION (93, 94).
