Abstract
The apparatus may be provided to improve a PAPR in at least one of a single-carrier FDM signal or DFT-s-OFDM. The apparatus may be 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; and transmit, to a second device, a signal based on the set of modulated symbols. An apparatus may be configured to receive, from a first device, a signal based on a set of modulated symbols and derive a set of encoded bits based on the received set of modulated symbols using a distribution matching function.
