High peak-to-average power ratio (PAPR) of the transmit signal is a major drawback of orthogonal frequency division multiplexing (OFDM). Selected mapping (SLM) technique is an efficient PAPR reduction technique for OFDM. In the SLM technique, many data blocks are generated from an OFDM data block using a set of phase sequences, and then the one with the lowest PAPR is chosen and transmitted. In this paper, an SLM technique with magnitude extension is proposed. In the proposed SLM technique, it is not needed to transmit side information from transmitter to receiver. The proposed technique achieves significant reduction in PAPR with only a small increase in transmit signal power.
