Abstract

Un método para determinar tonos reservados para reducción de una relación de potencia pico a promedio (PAPR) comprende: seleccionar índices de portadora para los tonos reservados y generar una señal de kernel basada en los índices de portadora seleccionados; calcular un valor promedio de referencia de comparación de la señal de kernel, seleccionar uno del valor promedio de referencia de comparación calculado y un valor promedio de referencia de comparación prealmacenado, y preliminarmente determinar índices de portadora de los tonos reservados con base en la selección; reacomodar un orden de los índices de portadora preliminarmente determinados; calcular un valor promedio de referencia de comparación de una señal de kernel generada, siempre que cada uno de los índices de portadora reacomodados sea cambiado a otro índice de portadora para generar una pluralidad de valores promedio de referencia de comparación, y finalmente determinar índices de portadora de los tonos reservados que generan una señal de kernel con el valor promedio de referencia de comparación más pequeño, entre los valores promedio de referencia de comparación, como los índices de los tonos reservados.
