Abstract
A method and apparatus for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system are provided. Reserved tones are determined, and the determined reserved tones are used to transmit a signal having an impulse characteristic in locations of sub-carriers that do not collide with a pilot signal of a preamble in a frame. The signal having the impulse characteristic is transmitted through the reserved tones in a symbol interval for which the preamble is transmitted.
Claims
exact text as granted — not AI-modified1 . A method for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system, comprising:
determining reserved tones used to transmit a signal having an impulse characteristic in locations of sub-carriers that do not collide with a pilot signal of a preamble in a frame; and transmitting the signal having the impulse characteristic through the reserved tones in a symbol period for which the preamble is transmitted.
2 . The method of claim 1 , wherein the digital broadcasting system uses Orthogonal Frequency Division Multiplexing (OFDM) as a transmission scheme, and locations of the reserved tones vary according to a Fast Fourier Transform (FFT) size.
3 . The method of claim 2 , wherein when the FFT size is 8K, locations of the reserved tones are determined in accordance with the following table:
