Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may apply a probabilistic amplitude shaping in discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) to a plurality of symbols to obtain a plurality of shaped symbols, wherein the probabilistic amplitude shaping is associated with a probability distribution with a steeper-than-Gaussian decay. The UE may transmit a signal associated with the plurality of shaped symbols. Numerous other aspects are described.
