An Improved PTS Method for PAPR Reduction Using Constellation Reshaping of OFDM Signals
Hongxiang Chu, Tetsuya Shimamura (Saitama Univ.) SIS2015-69
Abstract (in Japanese) (See Japanese page) 
(in English) Partial transmit sequence (PTS) is one of the most well-known techniques to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. However, a significant drawback of the conventional PTS is to transmit several side information bits. In this paper, we propose a new PTS method to reduce the PAPR without side information, which generates a set of new constellations. Corresponding to the new constellations with different phase factors, we can recover the original signal by using the proposed method at the receiver but not need side information in OFDM systems. Theoretical analysis and simulation results have shown that, compared with the conventional PTS, the proposed method could achieve further PAPR reduction of OFDM signals and provide a better bit error rate (BER) performance.
