Abstract

In orthogonal frequency division multiplexing (OFDM) systems, partial transmit sequence (PTS) scheme has been widely studied to mitigate the peak-to-average power ratio (PAPR) problem of OFDM signals. In this paper, an improved method to select dominant time-domain samples for PTS scheme is proposed to calculate the PAPR of OFDM signals efficiently. In the proposed selection method, it is performed adaptively at each time-domain sample to rotate time-domain subbolck samples. The PTS scheme using the proposed selection method can achieve almost the optimal PAPR reduction performance of PTS schemes with much lower computational complexity.
