Abstract

El procesamiento de senales de informacion separadas de acuerdo con la modulacion y los componentes de portadora en una manera mas controlada se hace posible mediante un dispositivo para procesar una senal de informacion (14) incluyendo medios (20) para convertir la senal de informacion (14) a una representacion tiempo/espectral mediante al transformacion en bloques de la senal de informacion y medios (22) para convertir la senal de informacion de la representacion tiempo/espectral a una representacion espectral espectral/modulacion, en donde los medios (22) para la conversion se disenan de tal forma que la representacion espectral espectral/modulacion depende tanto de un componente de magnitud como de un componente de fase de la representacion tiempo/espectral de la senal de informacion (14). Los medios (24, 40) realizan entonces una manipulacion y/o modificacion de la senal de informacion (14) en la representacion espectral espectral/modulacion para obtener una representacion espectral espectral/modulacion para obtener una representacion espectral espectral/modulacion modificada. Los medios adicionales (26) finalmente forman una senal de informacion procesada (18) que representa una version procesada de la senal de informacion (14) en base a la representacion espectral espectral/modulacion modificada.
