Abstract

Se proporciona un desmodulador para un receptor de datos digitales en paquetes en segmentos de tiempo predeterminados dentro de marcos de tiempo de longitud fija. El desmodulador comprende por lo menos un procesador de datos y es operativo para recibir los paquetes de datos que incluyen cada uno datos de sincronizacion. El desmodulador incluye una memoria temporal para almacenar datos de un paquete de datos recibidos, medios de procesamiento para leer por lo menos parte de los datos de sincronizacion tanto en el orden en que se recibieron los datos de sincronizacion como en el orden inverso y medios de formacion para formar el o cada procesador de datos dependiente de los datos de sincronizacion.
