Abstract

Se describen métodos y aparatos para procesar una señal que se transmite con una relación potencia pico - potencia promedio reducida. El procesamiento incluye aplicar (1650) un primer tipo de proyección de extensión de constelación de símbolos a por lo menos un símbolo en la constelación si se determina que un tipo de constelación es una constelación no cuadrada, el primer tipo de proyección de extensión de constelación de símbolos tiene una región angular hacia afuera desde una posición original para dicho al menos un símbolo en la constelación, la región angular hacia afuera definida por un valor para un ángulo entre una primera frontera y una segunda frontera para la región angular hacia afuera.
