Abstract

EL PROBLEMA DE LA SINCRONIZACION DE MARCOS DE IMPULSO APARECE POR EJEMPLO EN UN SISTEMA DE TELECOMUNICACION QUE TRABAJA SEGUN LA DISPOSICION STANDARD DECT CON APARATOS TERMINALES SIN HILOS. PARA EL AJUSTE DE UNA UNION FUNCIONAL ENTRE LA ESTACION BASE Y UN APARATO TERMINAL SIN HILOS SE EXPLORAN LAS CELDAS DE RADIO EN LA ESTACION BASE UNA DETRAS DE OTRA CON EL SOPORTE DE ALTA FRECUENCIA QUE SE ENCUENTRA A DISPOSICION EN EL RITMO DEL MARCO DECT. PARA GARANTIZAR UNA DISPOSICION CIRCUNDANTE DE LAS CELDAS MULTIPLES, QUE PERMITA LA EXPLORACION DE TODAS LAS ESTACIONES BASE AL MISMO TIEMPO CON LA MISMA FRECUENCIA, ES NECESARIO UNA SINCRONIZACION DE TODAS LAS ESTACIONES BASE PERTENECIENTES A LA INSTALACION DE TELECOMUNICACION SIN HILOS. ESTO SE CONSIGUE DE ACUERDO CON LA INVENCION POR MEDIO DE SUPRESION DE ECOS DE LOS IMPULSOS DE SINCRONIZACION DE MARCOS MULTIPLES DECT. LOS HUECOS DE IMPULSO SE VALORAN SIN LAS CONEXIONES PRESENTES DE RECONOCIMIENTO DE FALLO Y UTILIZAN SINCRONIZACION PSCN-, PRIMARY RECEIVER SCAN CARRIER NUMBER.
