Abstract	Partial transmit sequence (PTS) scheme has been widely studied to reduce the peak-to-average power ratio (PAPR) of Orthogonal frequency-division multiplexing (OFDM) signal since it is flexible and any spectral regrowth is not made. A necessity of the PTS scheme is to transmit the side information about the phase rotation factors for correct OFDM symbol recovery. In this paper, a new side information embedded PTS scheme using the reference symbols is proposed for the PAPR reduction and the BER performance is analyzed when the erroneous side information is received. In this proposed method, the information about the rotation factors is expressed by the phase of reference symbols. The proposed method maintains the same PAPR reduction performance as the conventional PTS scheme and OFDM symbols are correctly recovered by the side information to meet the required BER level. Also, the proposed method can be easily realized for all kinds of digital modulation formats in the OFDM communication system.
