Abstract :
Partial transmit sequences (PTS) is one of the most attractive schemes to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. However, the conventional PTS scheme requires an exhaustive searching over all combinations of allowed phase factors. Consequently, the computational complexity increases exponentially with the number of the subblocks. By utilizing the correlation among the candidate signals generated in PTS, a novel scheme is proposed to decrease the computational complexity. The performance analysis shows that the proposed scheme can reduce the computational complexity dramatically while achieving the same PAPR reduction compared to the conventional PTS scheme.
