Partial transmit sequences (pts) is a class of distortless papr reduction techniques for OFDM systems. However, the high complexity of pts remains a problem. In [5] the authors show that the papr reduction performance of pts is not as good as

reduction of peak-to-average power ratio (papr) in orthogonal frequency-division multiplexing (OFDM) system using the partial transmit sequence (pts) approach. In pts, the total search for the number of subblocks and the rotation factors must
