In a method for retrieving sequences having a minimum PAPR (peak to average power ratio) in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as "0" are calculated. A sequence having a minimum PAPR is selected from among the calculated PAPRs, and sequences allocated to the coset in which the selected sequence is included are retrieved as sequences having the minimum PAPR. In addition, according to PAPRs of sequences having early two elements fixed as "0" and the number of sequences of a coset including the sequences having early two elements fixed as "0," it is possible to quickly and efficiently analyze PAPR distribution of all sequences. Accordingly, the OFDM system can be designed as a device having a low PAPR and low dynamic range. |
