First Claim
1. A peak to average power ratio (PAPR) reduction method of a transmitter, the method comprising:
- generating a signal for reducing the PAPR of an orthogonal frequency division multiplexing (OFDM) symbol,wherein a fast fourier transform (FFT) size of the OFDM symbol is 16K, andwherein the generating generates the signal for reducing the PAPR of the OFDM symbol using a set of carriers having carrier indices listed below;

Abstract
A method of determining reserved tones for reduction of a peak to average power ratio (PAPR) includes: selecting carrier indices for the reserved tones and generating a kernel signal based on the selected carrier indices; calculating a comparison reference average value of the kernel signal, selecting one of the calculated comparison reference average value and a prestored comparison reference average value, and preliminarily determining carrier indices of the reserved tones based on the selection; re-arranging an order of the preliminarily determined carrier indices; calculating a comparison reference average value of a kernel signal generated, whenever each of the re-arranged carrier indices is changed to another carrier index, to generate a plurality of comparison reference average values, and finally determining carrier indices of the reserved tones which generates a kernel signal having the smallest comparison reference average value among the comparison reference average values as the indices of the reserved tones.
