Abstract
Un método para determinar tonos reservados para reducción de una relación de potencia pico a promedio (PAPR) comprende: seleccionar aleatoriamente índices de portadora para los tonos reservados y generar una señal de kernel basada en los índices de portadora aleatoriamente seleccionados para los tonos reservados; calcular un valor promedio de referencia de comparación de la señal de kernel, comparar el valor promedio de referencia de comparación calculado con un valor promedio de referencia de comparación prealmacenado, y preliminarmente determinar índices de portadora de los tonos reservados con base en la comparación; reacomodar un orden de los índices de portadora preliminarmente determinados de los tonos reservados; calcular valores promedio de referencia de comparación de señales de kernel generadas mediante el cambio de cada uno de los índices de portadora reacomodados de los tonos reservados y finalmente determinar índices de portadora de los tonos reservados que generan una señal de kernel que tiene el valor promedio de referencia de comparación más pequeño, entre los valores promedio de referencia de comparación, como los índices de los tonos reservados.
