Partial Transmit Sequence Scheme for Envelope Fluctuation Reduction in OFDMA Uplink Systems

IEEE Communications Letters, 2018
This letter proposes a new partial transmit sequence (PTS) scheme to reduce envelope fluctuations in orthogonal frequency-division multiple access (OFDMA) uplink systems. We found that the conventional PTS can be seriously degraded in the non-contiguous allocation of OFDMA uplink systems due to the linearity in the conventional phase rotations.

PAPR Analysis of OFDM using Partial Transmit Sequence Method

Journal of ISMAC, 2022
Orthogonal 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.

Fractional Subblocking for Partial Transmit Sequence OFDM

IEICE Transactions on Communications, 2008
Partial transmit sequence (PTS) is a well known technique used to reduce the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. However, it has relatively high complexity due to the computation of multiple inverse fast Fourier transforms (IFFTs).

Phase factor sequences algorithm in partial transmit sequence

Transactions of Tianjin University, 2009
Partial transmit sequence (PTS) is a promising technique for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM). While in optimal PTS, an exhaustive search for all combinations of phase factor sequences is required, this results in huge computation.

Comparing Selected Mapping and Partial Transmit Sequence for PAR Reduction

IEEE Transactions on Broadcasting, 2007
Selected mapping (SLM) and partial transmit sequence (PTS) are two existing distortionless peak-to-average power ratio (PAR) reduction schemes that have been proposed for orthogonal frequency division multiplexing (OFDM). Previously, it was argued that SLM and PTS have comparable PAR reduction performance but that the latter has lower computational ...
