Abstract
EN UN SISTEMA DE RECEPCION DIVERSITY Y UN SISTEMA DE ANTENAS PARA LA RECEPCION MOVIL, SOBRE TODO PARA RECEPCION DE RADIO EN AUTOMOVILES, SE TOMAN PRUEBAS DE MUESTRA DE LAS DIFERENTES SEÑALES DE COMBINACION LINEALES O DE ANTENAS, QUE A CONTINUACION SON MODULADAS POR UNA SEÑAL DE MODULACION DE AYUDA Y UNA SEÑAL DE SUMA FORMADA POR LAS SEÑALES DE COMBINACION. UNA VEZ QUE ESTAS SEÑALES DE SUMA HAN SIDO DEMODULADAS, PUEDEN SER UTILIZADAS PARA EL AJUSTE DE LOS ELEMENTOS DE GIRO DE FASES PARA LA SUMA DE RENDIMIENTO OPTIMA, PERO SOBRE TODO PARA DESCONECTAR UNA SEÑAL DE COMBINACION DEL SISTEMA DE ANTENAS TOTAL Y ASI EVITAR REFLESIONES DE RENDIMIENTO Y ENTRADAS CON UNA FUERZA DE SEÑALES PEQUEÑAS.
