A novel subblock partition scheme for partial transmit sequence OFDM
IEEE Transactions on Broadcasting, 1999In general, there has been a trade-off between performance of peak-to-average power ratio (PAPR) reduction and computational complexity in partial transmit sequence (PTS) orthogonal frequency division multiplexing (OFDM). In this paper, a novel subblock partition scheme (SPS) for PTS OFDM is proposed and analyzed.

Randomization Algorithm for Partial Transmit Sequence with Semidefinite Relaxation
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018To reduce peak-to-average power ratio is a significant task for Orthogonal Frequency Multicarrier Systems. In this paper, we propose a method to choose a suitable vector for a partial transmit sequence technique. Our method is to generate random vectors from the Gaussian distribution whose covariance matrix is a solution of a relaxed problem and to ...

Decoupled Phase Optimization for Partial Transmit Sequence OFDM
2009 IEEE Wireless Communications and Networking Conference, 2009Partial transmit sequence (PTS) is a proven technique for peak-to-average-power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. Determining the optimal phase factors requires an exhaustive search over all possible sets of phase factors. Hence, simplified optimal and suboptimal approaches have been proposed. Previous
