The algorithm of Partial Transmit Sequence (PTS) technique has high computational complexity in Orthogonal Frequency Division Multiplexing (OFDM) system. In this paper, a new low-complexity combined subblock segmentation method for PTS OFDM is proposed. For analytic purposes, we derive computational complexity expressions for the proposed segmentation method and analyze the computational complexity of the proposed segmentation method compared with that of the random segmentation method which has the best Peak to Average Power Ratio (PAPR) reduction performance. The simulation results show that the PAPR reduction performance is degraded only slightly compared with random segmentation method.
