Abstract:

Multicarrier faster-than-Nyquist (MFTN) signaling achieves spectral-efficient transmissions through simultaneous compression in the time and frequency domains. However, it brings the problem of high peak-to-average power ratio (PAPR). In this study, we propose a novel scheme by element-wise phase rotations (EPR) and subcarrier-wise phase rotations (SPR) to reduce the PAPR of MFTN signal. Specifically, the EPR applies phase rotations to different elements (symbols) on subcarriers, while the SPR introduces different phase terms among different subcarriers. Such a simple scheme is motivated by the fact that introducing additional phase terms in the summation will be likely to decrease the sum value. Numerical results indicate that the proposed EPR-SPR combined scheme improves the PAPR performance of MFTN signaling.
