Abstract

Un dispositivo de comunicacion (300) incluye un modulador digital (301), un Procesador de Señal Digital (306), y un amplificador (312). El modulador digital (301) incluye un generador de informacion (304) y un dispositivo de supresion de pico (402). El dispositivo de supresion de pico (402) incluye un proyector de símbolo (404) y un escalador de símbolo (406). La informacion generada por el generador (401) se proyecta en un diagrama de constelacion a través del proyector de símbolo (404). La informacion proyectada se gradua entonces en el escalador (406) con objeto de reducir la proporcion de pico a promedio de la señal en la entrada al amplificador (812).
