Abstract

This paper proposes a new peak-to-average power ratio (PAPR) reduction technique for OFDM systems. The proposed system selects the specific duration of each time-domain OFDM symbol which can achieve a promising PAPR, to transmit equal bits of data. Compared with the OFDM system using amplitude clipping, PST can obtain comparable PAPR performance and achieve a 0.5 - 3 dB BER performance gain by choosing the appropriate parameters. In addition, PST does not need any complex modules to fix the original phases of the clipped samples, so it decreases the cost of transmitters.
