Abstract

Se describe un conmutador digital incluido dentro de un satélite, procesos de los haces de enlace ascendentes y los canales de tráfico incluidos en un nivel de símbolos, en lugar de un nivel de bits. En este sistema, el conmutador se comporta como un repetidor en una base por usuario y como un conmutador en el nivel del haz. Las señales del usuario individuales (i.e., canales) se separan del haz de enlace ascendente y se recombinan en el haz de enlace descendentes adecuado.
