CPC H04L 27/2615 (2013.01) [H04L 27/2636 (2013.01)] | 28 Claims |
1. An apparatus 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) at a first device, comprising:
memory; and
at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
encode a set of information bits with a channel encoder;
generate, based on a set of encoded bits from the channel encoder, a set of amplitude symbols using a distribution matching function;
generate 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
transmit, to a second device, a signal based on the set of modulated symbols.
