Low-Complexity Selective Mapping Methods for Multicarrier Faster-Than-Nyquist Signaling
IEEE Access, 2020 Multicarrier faster-than-Nyquist (MFTN) signaling is a high spectral efficiency transmission scheme, which is promising in the future communication. One of the major problems of MFTN signaling is high peak-to-average power ratio (PAPR).

A novel frequency-domain implementation of Tomlinson-Harashima precoding for SC-FDMA [PDF]
, 2009 There is considerable interest in the use of single carrier frequency division multiple access (SC-FDMA) as the uplink transmission scheme in the 3GPP Long Term Evolution standard. This interest is justified by the inherent single carrier structure of SC-

Frequency-Selective PAPR Reduction for OFDM [PDF]
, 2019 We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...
