Abstract:
Methods and apparatuses are provided for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system. Reserved tones are determined in previously determined locations of sub-carriers that do not collide with a pilot signal of a preamble in a frame. A signal is transmitted through the reserved tones in a period for which the preamble is transmitted. If a Fast Fourier Transform (FFT) size is 8K, locations of the reserved tones are determined in accordance with a specified chart.
