Abstract
EN EL DOMINIO DE TIEMPO DE LAS COMUNICACIONES DE ACCESO MULTIPLE DE DOMINIO MULTIPLEX/DE TIEMPO ENTRE UNA ESTACION DE BASE Y UNA UNIDAD DE ABONADO, LA ESTACION DE BASE ENVIA UNA SEÑAL DE REFERENCIA DE SINCRONIZACION. UNA UNIDAD DE ABONADO RESPONDE CON UN PAQUETE DE DATOS (A) SUFICIENTEMENTE CORTO PARA ASEGURAR SU RECEPCION CORRECTA POR LA BASE INDEPENDIENTEMENTE DEL TIEMPO DE TRANSMISION. LA BASE DETERMINA EL TIEMPO DE TRANSMISION EMPLEADO Y ORDENA A LA UNIDAD DE ABONADO QUE MEJORE SUS SINCRONIZACIONES DE MANERA QUE LOS PAQUETES DE DATOS MAS LARGOS (B) PUEDAN SER ENVIADOS PARA SER RECIBIDOS CUANDO SEA PREVISTO. EL AJUSTE DE SINCRONIZACION INCLUYE UN COMPONENTE PRESENTE FIJO DEPENDIENTE DE LA SEPARACION APROXIMADA DE LA ESTACION DE BASE Y DE LA UNIDAD DE ABONADO, Y UN SEGUNDO COMPONENTE DE MEDICION DEL TIEMPO DE TRANSMISION EMPLEADO.
