Abstract

EN UN PROCEDIMIENTO RECEPTOR Y SISTEMA DE RECEPCION DE ANTENA PARA LA RECEPCION MOVIL SEGUN EL METODO DIVERSITY DE SELECCION DE ANTENAS SE TOMAN CADA UNA DE LAS SEÑALES DE ANTENA DE CADA SEÑAL DE PRUEBA, LA SECUENCIA DE UNA MODULACION SOMETIDA Y UNA SEÑAL DE ANTENA SELECCIONADA EN LA LONGITUD SON INCREMENTADAS A UNA SEÑAL DE SUMA, A LA QUE ES CONDUCIDO UNA CONEXION DE RECEPCION. LA SEÑAL DE SUMA AMPLIFICADA EN LA CONEXION DE RECEPCION Y SELECCIONADA SE DEMODULA Y DE ESTA SE TRANSMITE UNA SEÑAL DE PRUEBA AMPLIFICADA QUE POSTERIORMENTE SIRVE COMO CRITERIO PARA LA SELECCION DE LAS CORRESPONDIENTES SEÑALES DE ANTENAS O COMBINACIONES LINEALES AMPLIFICADAS. ALTERNATIVAMENTE O ADICIONALMENTE SE TRANSMITE LA PARTE DE LA SEÑAL DISTORSIONADA Y COMO UNICO O ADICIONAL CRITERIO ES TOMADO PARA LA SELECCION DE LA SEÑAL.
