A Novel PAPR Reduction Scheme for Low-Cost Terminals in 6G

This paper presents a low peak-to-average power ratio (PAPR) modulation scheme and demodulation method for low-cost terminals in sixth-generation (6G), which is called one plus delay (1 + D) pi/2(N 1) BPSK. Explicitly, the first generated based on pi/2 BPSK, then proceeded by interpolation transformation. Simulation results show that proposed BPSK has lower PAPR smaller out-of-band leakage discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM). Moreover, better performance can be attained increasing value of N. Finally, similar block error (BLER) obtained at same spectral efficiency conventional scheme.
