Abstract: A channel encoding method in a communication or broadcasting system is provided. The channel encoding method includes reading a first sequence corresponding to a parity check matrix, converting the first sequence to a second sequence by applying a certain rule to a block size corresponding to a parity check matrix and the first sequence, and encoding information bits based on the second sequence. The block size has at least two different integer values.

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.
