Abstract

Sistema para incrementar la capacidad de las redes de distribución de señales de frecuencia intermedia de satélite, de los que constan de una cabecera que recibe los canales (CH) con las señales originales en formato QPSK, las procesa y las envía a un conversor que envía sus señales de salida al receptor del usuario, caracterizado porque en la cabecera se procesan al menos algunos de los canales (CHP) a formato QAM y porque el conversor convierte el formato de modulación QAM en formato de modulación QPSK. De aplicación en televisión digital.
