Abstract
QUE APLICADO EN SISTEMAS DE COMUNICACIONES DIGITALES SIN HILOS CON ACCESO MULTIPLE POR DIVISION EN EL TIEMPO, ENTRE UN TERMINAL SIN HILOS Y SU ESTACION BASE, SE CARACTERIZA PORQUE DICHO TERMINAL ADELANTA EL INSTANTE DE EMISION DE SUS RAFAGAS RESPECTO DE LA REFERENCIA OBTENIDA A PARTIR DE LA ESTACION BASE EN CASO DE NO RECIBIR RESPUESTA POR PARTE DE LA ESTACION BASE A UNA PRIMERA RAFAGA ENVIADA POR EL TERMINAL A SU ESTACION, EN FORMA AUTOMATICA EN UN NUMERO CONSTANTE DE BITIOS CADA UNO HASTA LOGRAR SU CORRECTA SINCRONIZACION CON SU ESTACION BASE EN CASO DE QUE CONTINUE SIN RECIBIR RESPUESTA; CUANDO ESTA ES RECIBIDA SE CONSIDERAN SINCRONIZADOS CON LAS ESTACIONES BASE DENTRO DEL PLAZO ESTABLECIDO DE TIEMPO, A LA RAFAGA ENVIADA A LAS ESTACIONES BASE
