PAPR Reduction of Multicarrier Faster-Than-Nyquist Signals With Partial Transmit Sequence
IEEE Access, 2017 Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient transmission scheme for future communication systems. Similar as general multicarrier signals, the high peak-to-average power ratio (PAPR) is also one of the main drawbacks of MFTN
