Abstract

Un método para determinar tonos reservados para utilizarse 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; 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 aleatoriamente un orden de los índices de portadora preliminarmente determinados de los tonos reservados; y calcular el valor promedio de referencia de comparación mientras se cambia cada uno de índices reacomodados de los tonos reservados, y finalmente determinar los índices de portadora para los cuales el valor promedio de referencia de comparación calculado se convierte en el valor más pequeño como los índices de los tonos reservados.
