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.

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).

A novel subblock partition scheme for partial transmit sequence OFDM

IEEE Transactions on Broadcasting, 1999
In 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.

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 ...

Partial transmit sequences for PAPR reduction of OFDM signals with stochastic optimization techniques

IEEE Transactions on Consumer Electronics, 2010
This paper considers the use of the partial transmit sequence (PTS) technique in reducing the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. The conventional PTS technique is highly successful in PAPR reduction for OFDM signals, but the considerable computational complexity for the required search ...
