Improved Algorithm of Partial Transmit Sequence Based on Discrete Particle Swarm Optimization

open access: yesMathematics, 2023
Orthogonal frequency division multiplexing (OFDM) in 5G has many advantages; however, one of the disadvantages is that the superposition of a large number of subcarriers leads to a high peak-to-average power ratio (PAPR) of the transmit signal.

PAR reduction of an OFDM signal using partial transmit sequences [PDF]

open access: yesIEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002
The peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal can be substantially larger than that of a single carrier system. Partial transmit sequence (PTS) combining can improve the PAR statistics of an OFDM signal. For PTS, the search complexity increases exponentially with the number of subblocks. We present

Performance analysis of pre-equalized multilevel partial response schemes [PDF]

open access: yes, 2015
In order to achieve high speed on electrical interconnects, channel attenuation at high frequencies must be dealt with by proper transceiver design. In this paper we investigate finite-complexity MMSE pre-equalization under an average transmit power ...

Low-Complexity Partial Transmit Sequence Methods Using Dominant Time-Domain Samples for Multicarrier Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2019
In Multicarrier faster-than-Nyquist (MFTN) systems, one of the most important problems of MFTN signaling is high peak-to-average power ratio (PAPR). In this paper, partial transmit sequence (PTS) method is adopted to resolve this problem, and we focus on
