Abstract

PROCEDIMIENTO DE ALINEAMIENTO DE RAFAGAS. PROCEDIMIENTO DE ALINEAMIENTO DE RAFAGAS ENTRE TERMINALES SIN HILOS (T) Y SUS ESTACIONES BASE (BS), A PARTIR DE LAS CUALES DICHOS TERMINALES SIN HILOS (T) OBTIENEN LA REFERENCIA DE SU BASE DE TIEMPOS. DICHO PROCEDIMIENTO DE ALINEAMIENTO DE RAFAGAS ES APLICABLE EN SISTEMAS DIGITALES DE COMUNICACIONES SIN HILOS CON ACCESO MULTIPLE POR DIVISION EN EL TIEMPO, PARA ASEGURAR LA CORRECTA RECEPCION DE LAS RAFAGAS RECIBIDAS CON DIFERENTES RETARDOS DEBIDOS A EFECTOS DE LA PROPAGACION. EN DICHO PROCEDIMIENTO, LOS TERMINALES SIN HILOS (T) RETRANSMITEN SUCESIVAMENTE, HASTA UN NUMERO MAXIMO DE VECES, UNAS PRIMERAS RAFAGAS HACIA SUS ESTACIONES BASE (BS), ADELANTANDOLAS CADA RETRANSMISION EN UN NUMERO CONSTANTE DE BITIOS, DEPENDIENDO DEL TAMAÑO DEL ESPACIO DE GUARDA ENTRE CANALES, HASTA QUE RECIBAN RESPUESTA DE SUS ESTACIONES BASE (BS) AL ESTAR SINCRONIZADOS CORRECTAMENTE CON ESTAS.
