Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may generate a phase-ramped modulated data stream with a set of phase-shift keying (PSK) modulated symbols, wherein a phase-ramped modulation is applied to the set of PSK modulated symbols in a pre-discrete-Fourier-transform (pre-DFT) domain. The network node may transmit, to a user equipment (UE), the phase-ramped modulated data stream. Numerous other aspects are described.
