In this letter, we propose a novel peak-to-average power ratio (PAPR) reduction scheme based on orthogonal pilot sequence (OPS) for orthogonal frequency division multiplexing (OFDM) systems. We change the pilot symbols' phases iteratively according to a set of orthogonal sequences, and use the phases of the pilot subcarriers as the phase factors for data subcarrier groups. The proposed scheme can achieve up to three times more PAPR reduction compared to the conventional schemes without sacrificing side information (SI)-free transmission.
