Abstract

Un método de reducción de potencia pico a promedio incluye: (a) modular por amplitud en cuadratura una señal que incluye un conjunto de subportadores con un conjunto de datos para producir un vector de símbolo modulado OFDM; (b) limitar la magnitud del vector símbolo modulado para producir un primer símbolo modulado OFDM limitado; (c) desmodular el primer símbolo modulado OFDM limitado para recuperar constelaciones QAM distorsionadas; (d) restringir puntos en las constelaciones QAM distorsionadas recuperadas del primer símbolo modulado OFDM limitado para producir constelaciones QAM restringidas; (e) modular un vector de símbolo OFDM con las constelaciones QAM restringidas para producir un símbolo OFDM modulado modificado; y (f) sacar el símbolo OFDM modulado modificado. Se proporciona también un transmisor que implementa el método.
