Abstract

Con la introducción de la tecnología de multiplexión por división de frecuencia ortogonal (OFDM) en los canales de comunicación en una red de cable, módems de cable que reciben datos aguas abajo sobre subportadoras del canal OFDM se agrupan en niveles de modulación con base en al menos una métrica. Un perfil se genera para cada canal OFDM con base en las mediciones a través de módems de cable y subportadoras relacionadas con el canal OFDM, incluyendo los valores de métrica utilizados para agrupar los módems de cable en los niveles de modulación. Incluido en un perfil de OFDM puede haber un esquema de asignación de módems de cable marginales en la pluralidad de niveles de modulación. Los métodos y sistemas para generar perfiles de esquema de modulación y codificación permiten una modulación más eficiente por medio de los elementos de red.
