Classification: CPC H | IPC H

Claim 15:
16. A method, at a first device for wireless communication, to improve a peak to average power ratio (PAPR) in at least one of a single-carrier frequency division multiplexed (FDM) signal or discrete Fourier transform (DFT) spread orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM), the method comprising:
encoding a set of information bits with a channel encoder;
generating, based on a set of encoded bits from the channel encoder, a set of amplitude symbols using a distribution matching function;
generating a set of modulated symbols based on the set of amplitude symbols, wherein the set of amplitude symbols indicates a set of phases that are used to generate the set of modulated symbols; and
transmitting, to a second device, a signal based on the set of modulated symbols.
