Abstract
Se describe, en un sistema (100) de radiocomunicacion, la provision de una capacidad de comunicacion mejorada, en tanto que se mantiene la compatibilidad de modulacion del canal estándar. En un transmisor (110, 200, 600) una primera señal de informacion se genera a partir de los datos, de acuerdo a un esquema (212, 613) de modulacion estándar predefinido. Una segunda señal de informacion se genera a partir de los datos que proveen informacion complementaria a los datos modulados estándar (213, 616). Para la transmision, las primeras y segundas señales de informacion se combinan en una señal compuesta (214, 619) que representa la primera señal de informacion cuando se interpreta de acuerdo al esquema de modulacion de canal predefinido.
