In this paper, we propose a new subblock division method(SDM) for PAPR reduction in the OFDM communication system. The SDM divides the OFDM symbol into the several subblocks. If the PAPR is high, the some of the data subblocks are replaced by the dummy zero padding blocks. We propose SDM 1 and SDM 2 according to the structure. Even though the transmission efficiency may be partially lowered, the proposed SDM can considerably reduce the computational burden while maintaining similar PAPR reduction performance, compared with the PTS which is known to be the best in the conventional methods.
