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

On partial transmit sequences for PAR reduction in OFDM systems
IEEE Transactions on Wireless Communications, 2008Partial transmit sequences (PTS) is a popular technique to reduce the peak-to-average power ratio (PAR) in orthogonal frequency division multiplexing (OFDM) systems. PTS is highly successful in PAR reduction and efficient redundancy utilization, but the considerable computational complexity for the required search through a high-dimensional vector ...

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 ...

Repetition Code Subblocking for Partial Transmit Sequence OFDM
2008 IEEE International Conference on Communications, 2008Partial transmit sequence (PTS) is a proven technique to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. It achieves significant PAPR reduction without distortion, but the high computational complexity of multiple Fourier transforms is a problem in practical systems. In this paper, we consider

PAPR Distribution Analysis of OFDM signals with Partial Transmit Sequence
Journal of Communications, 2011Third Generation Partnership Project (3GPP) LTE has adopted OFDMA as the uplink multiple access scheme. One of the major drawbacks is the high PAPR. Not only is the performance of PAPR with PTS technique influenced by the number of subblocks and the phase vector but also by the subblock partitioning.

Blind Detection of Partial Transmit Sequence in a Coded OFDM System
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009PAPR reduction is an important issue in wireless OFDM transmission. Partial transmit sequence (PTS) is one of the distortionless methods. However, PTS requires side information on the phase rotation. This impacts not only the transmit efficiency but also the standardization process.

PAPR Analysis of OFDM using Partial Transmit Sequence Method
Journal of ISMAC, 2022Orthogonal Frequency Division Multiplexing (OFDM) is one of the most widely used multicarrier transmission and effective technologies in today's communication networks. OFDM has many benefits and drawbacks. High Peak to Average Power Ratio (PAPR) is one of its main drawbacks.

The optimization arithmetic for power allocation scheme on partial transmit sequences
14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004The performance of the system with partial transmit sequences is dominated by the side-information. On the premise of that the total transmitting power is limited, the authors investigate the effect of different power allocation schemes between the data and side-information. The arithmetic to obtain the optimal power allocation coefficient is proposed.

Decimation-in-Time FFT Subblocking for Partial Transmit Sequence OFDM
2007 IEEE 66th Vehicular Technology Conference, 2007We consider an IFFT-based technique for reducing the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. The intermediate signals in a radix decimation-in-time (DIT) algorithm is used for subblock partitioning in the partial transmit sequence (PTS) technique.
