摘要：
The development of 5G and 6G networks is impossible without improving spectral efficiency. Faster than Nyquist (FTN) signaling allows increasing symbol rate of transmission and may be applied both to multicarrier and single-carrier signals. However, it leads to uncontrollable intersymbol interference in the time domain. Optimal FTN signaling assumes application of optimal pulses obtained as a solution of an optimization problem and provides controllable intersymbol interference. In this paper, we propose to investigate peak-to-average power ratio (PAPR) of single-carrier optimal FTN signals obtained with the constraint on the minimum Euclidean distance. Comparison with FTN signals based on root-raised-cosine pulses shows that optimal FTN signals provide the gain in PAPR about 2 dB at the same bit rate.
